Chapter Chatter
Where there is smoke, there is . . .
Chuck Kendall is a Senior EMC Consultant with CKC Laboratories, Inc. in Mariposa, California. In his early days of EMC, he was asked to attend a military test with his brother, the late Chris Kendall. In the process of ‘gaining some experience,’ he had quite an experience. I think the story is the most humorous told from Chuck’s perspective.
“My brother, Chris, invited me to tag along on a military project at Raytheon in Santa Barbara. Arriving early, we signed in and received our escort badges. We soon arrived at one of their large EMC labs, where one of their systems was set up and ready to test. Chris spoke with the Raytheon project engineers to clarify what tests we were to perform that day. If my memory serves me right, I was assigned to perform a magnetic loop probe test (MIL-STD-461A for the Navy), with one of the Raytheon engineers assigned to support me.
Some time after Chris got me started testing, he came up to me and said, ‘I need to go to another room and assist an engineer with a different project. Just keep on doing what you’re doing and I’ll be right back.’ With that he and the Raytheon engineer walked off. So, I kept monitoring the magnetic test. Then, ‘my’ engineer said he had to retrieve a needed item and he too would be right back. He informed me that if anything out of the ordinary happened, just push the emergency shut off button. He pointed out the location of the button to make sure that I understood where it was.
Once he was gone, I went back to monitoring the test. Just then, I began smelling something cooking and it wasn’t even close to lunchtime. As I turned around to check out the system I was testing, whispers of smoke were emanating from the vents in a bottom panel. Remembering my last instructions, I reached for the large, red emergency shut-off button. The power instantly went off and the smoking stopped. As the smoke was clearing, I heard a commotion in the hallway, outside the room I was working in. ‘How did they know that the system I was working on would go down’ I was wondering. I also recalled that I was there alone, although I was supposed to be under constant escort. So, not wanting to reveal my delicate situation, I listened quietly at the door until I heard a voice that I thought I recognized. I cautiously opened the door and found myself looking into a hallway of about 20 people. When we arrived earlier, the sight of four people would have been a crowd. I became less worried about where my escort was, for I suddenly had plenty of escorts. All at once, ‘my’ engineer barged by me like I was a flowerpot, and informed everyone who was listening, that all of the systems on this side of the building had been shut down as well.
‘My’ engineer then asked me why I pushed the big red button and in the process caused all of the commotion. In reply, I pointed to the bottom panel of the system, and told him that because the device was smoking, I hit the emergency shut-off. He then asked, ‘well, how much smoke was coming out of the system?’ Having recently retired from active duty Air Force, in the nuclear weapons field, I was trained to take any indication of smoke very seriously. So, I took his inquiry seriously and described the amount of smoke to him in a serious fashion. After hearing me out, ‘my’ engineer said to everyone within earshot that the whole occurrence was probably part of normal operation. And, having said that, he confidently switched the power to the system back on. It wasn’t very long before the system responded; only this time no one had to push the big red button. After an exciting electrical pop, the system shut down all on its own. Once the initial bewilderment wore off, ‘my’ engineer hurriedly removed the panel cover to investigate. The first thing we all noticed is that the ribbon cables that were draped over the three phase EMC filter were different in color and form. Shades of black were evident in the fragments of cable that were left dangling. What was previously a four-pole filter was now a three-pole filter. An entire pole of the filter was gone along with much wiring!
Needless to say, my test project came to an abrupt halt. In the car on the way home, I asked Chris to never again leave me at a customer site until I had more experience. After such an introduction, I thought that my first military test was going to be my last.”


Australia – Welcome New Chapter!
Welcome to the newly founded Victoria IEEE EMC Chapter in Australia! The Chairman of the Victoria Chapter is Malcolm Mulcare, The EMC Society Board of Directors, Chapters, and Members welcome this newly formed EMC Chapter. Good luck to the Chapter, its Chairman, and Officers!

Professor Fujiwara, last year’s Chapter Chair, reports that the IEEE EMC-S Japan Chapter holds regular technical meetings ten times per year in cooperation with the IEEE EMC Society Sendai Chapter. These meetings are also co-sponsored by the EMC Technical Group of the Institute of Electronics, Information, and Communication Engineers (IEICE). In addition, some non-regular technical meetings such as an EMC workshop and joint meeting in Asia are also held. More than 150 technical reports are normally presented every year. In 2005, 172 papers were presented as follows: On January 20–21, March 10, April 22, May 25 -26, June 9–10 and July 28-29, the technical committee meetings on EMC were held in NICT Okinawa, Tokyo, Kanagawa, Awaji-island, Sapporo and Tokyo, respectively.

Bruce Crain, Melbourne EMC Chapter Chair, reports that on February 27, the Melbourne EMC chapter hosted the “Aerospace EMC Tech Tour” at the Hilton Melbourne Rialto Place Hotel in Melbourne, Florida. ETS-Lindgren, Rohde & Schwarz, and Conformity Magazine sponsored this event. Speakers were James Young of Rohde & Schwarz, Vince Rodriguez of ETS-Lindgren, and Ken Javor of EMC Compliance. This half-day seminar drew about 50 attendees from the local area. Ken Javor started things out with a presentation on “Mil-Standard EMC Testing of Products and Aircraft,” focusing on CS114, RE101 and RE102 testing. Ken is a member of the MIL-STD-461 technical committee and brought a wealth of historical perspective to the origins and rationale of these tests. Vince Rodriguez then gave a presentation on “Anechoic Chamber Solutions for Antenna Pattern Measurements.” Vince has a great deal of experience in the design of anechoic chambers and gave a comprehensive overview of the types of anechoic chambers used for antenna pattern measurements. James Young rounded out the day’s presentations with a discussion about “Improving the Accuracy of EMI Measurements.” He discussed the subtleties of using spectrum analyzers for EMI measurements versus tuned EMI receivers, as well as issues associated with achieving low noise EMI measurements. After the day’s technical presentations, everyone enjoyed a complimentary reception with a drawing for some very nice door prizes, including gift cards, memory sticks, a DVD player and an iPod Nano. The Melbourne Chapter thanks the corporate sponsors, the speakers, and Janet O’Neil of ETS-Lindgren, for making the local arrangements.

Oregon and SW Washington
William Moyer reports that the Oregon and SW Washington Chapter started their first quarter 2006 technical presentations program with a presentation at the University of Portland in January by Jim Skelly on the increasingly important topic of “Coated Plastics in EMC Applications.” President of Cybershield since 2001, Jim received an Industrial Engineering degree from the University of Rhode Island and an MBA from Northeastern University. Jim worked for Texas Instruments for over 20 years in sales, marketing, and program management positions. After leaving TI, he was Sales VP at Airborn, a leading high reliability connector manufacturer, was President of Thermalloy, an electronic component manufacturer, and was President of EL Specialists, a start-up that developed an innovative electro luminescent technology. Use of conductive coatings in EMI shielding systems is expanding due to the growing use of injection molded plastic enclosures and components in today’s electronic devices. Faster semiconductor clock speeds are increasing the challenges for robust EMI shielding systems, while electronic device form factors are continuing to shrink. Plastics being non-conductive by nature, plastic enclosures do not mitigate EMI without incorporation of conductive shielding materials to meet regulations and to ensure reliable device performance. Conductive coatings essentially consume no volume inside an electronic device and if applied properly can assist design engineers in meeting cost targets. The presentation reviewed the shielding effectiveness of many conductive coatings systems and included information on design considerations for effective utilization of conductive coatings in electronic devices. The presentation concluded with a review of several current production applications and their EMI shielding systems. At the February Chapter Meeting, Dr. Robert G. Olsen presented a “Technical Overview of Broadband Powerline (BPL) Communication Systems,” the subject of much of his current work. Associate Dean of the College of Engineering and Architecture and the Boeing Distinguished Professor of Electrical Engineering at Washington State University, Pullman, WA, USA, he received his BS degree in electrical engineering from Rutgers University in 1968 and MS and Ph.D. degrees in electrical engineering from the University of Colorado, Boulder in 1970 and 1974 respectively. Professor Olsen has been a member of the electrical engineering faculty at Washington State University since 1973. During that time he has been a visiting scientist at GTE Laboratories in Waltham, MA, at ABB Corporate Research in Västerås, Sweden and at EPRI in Palo Alto, CA and a Visiting Professor at the Technical University of Denmark. Dr. Olsen is a Fellow of the IEEE and presently serves as Technical Editor of the IEEE Electromagnetic Compatibility Society Newsletter, and as Co - Technical Program Chair of the 2005 Electromagnetic Compatibility Conference in Zurich, Switzerland. He is the past United States National Committee representative to CIGRE Study Committee 36 (Electromagnetic Compatibility) and past chair of the IEEE Power Engineering Society AC Fields and Corona Effects Working Groups. He is also past Associate Editor of the IEEE Transactions on Electromagnetic Compatibility and Radio Science. His research interests include electromagnetic interference from power lines, the electromagnetic environment of power lines, electromagnetic wave propagation, electromagnetic compatibility and electromagnetic scattering. His work in these areas has resulted in approximately 75 publications in refereed journals. His most recent work has been supported by the Bonneville Power Administration, the Boeing Defense and Space Group, the Electric Power Research Institute, the National Science Foundation and the U.S. Navy. Presenting his overview on a technology now perhaps coming into being on the telecommunications frontier, Professor Olsen gave an informative and quite interesting presentation on two of the primary technical challenges to proposed use of the electric power transmission and distribution system as a transmission medium for broadband powerline (BPL) communications. Since the power system was not designed for this purpose, there are significant technical hurdles to be overcome before BPL systems can be successfully implemented. The first significant technical difficulty discussed was the relatively high channel attenuation rate due to discontinuities such as taps, transformers, and other devices connected to the system. The second difficulty discussed was system unbalance and its dominant effects on meeting government-regulated limitations on electromagnetic emissions. The potential profitability of a BPL system being affected by both phenomena, successful implementation of any wide-scale BPL system will likely prove more than a little challenging, as Professor Olsen’s presentation made abundantly clear. In March, Portland was host to Dr. David Pommerenke, who gave a presentation on “Advanced ESD and EMI Analysis Methods.” Dr. Pommerenke received his diploma and Ph.D. at the Technical University Berlin, Germany where he continued as a post-doctoral student for two years before continuing at Hewlett Packard in Roseville, CA for five years. Since 2001, he has been a faculty member at the University of Missouri at Rolla in the Electromagnetic Compatibility group. Dr. Pommerenke combines knowledge from the fields of electronics, test instrument design, and electromagnetics. His current research includes the development of measurement systems, high-speed electronics design, signal integrity and electromagnetic compatibility, especially the analysis and mitigation of unwanted disturbances of systems by EMI events, such as electrostatic discharge and others. There special emphasis is given to the interactions of all of the components that form an electronic system: shielding, PCB, IC design and software performance. He has published some 100 articles on topics from high voltage systems, EMC and instrumentation, and is an inventor in seven patents. There being no single method that allows identifying all reasons for EMI and ESD problems, one needs to be aware of and have experience in a variety of methods, to apply the hopefully most suitable method to the problem at hand. This presentation offered a look at analysis methods for ESD and EMI. The presentation on ESD analysis addressed PCB level scanning to identify sensitive nets on PCB’s and explained how (and when) this relates to IC level and system level test results. The presentation also discussed the relationship between ESD protection circuits, upset, and destruction errors. Next turning to problems of EMI analysis, the presentation discussed how finding sources and antennas is usually not a problem in EMI, but understanding and quantifying the coupling path is sometimes close to impossible. The presentation discussed the use of port impedances and transfer functions for determining coupling paths and for the measurement of very hard to measure currents (specifically common mode current on a differential trace). Many members of the Oregon-SW Washington chapter are keeping busy with preparations for the 2006 IEEE International Symposium on EMC in Portland, Oregon. Papers for the technical sessions and workshops have been reviewed and accepted. The technical program committee is pleased to announce that EMC 2006 will be on the cutting edge of EMC information, with papers backed by solid research and development. Please visit the EMC 2006 Website at for more information. The Oregon-SW Washington Chapter looks forward to having you participate in “Exploring EMC Frontiers” this summer in Portland!

The IEEE EMC Phoenix Chapter was proud to host the January 2006 RF-EMC-Wireless Tech Tour at the Embassy Suites Hotel in Tempe, Arizona. The RF-EMC-Wireless Tech Tour is an on-going series of technical learning sessions that will travel to Melbourne, Florida, the Metro D.C. area, and to Boston, Massachusetts later this year. Registration began promptly at 12:30 and it was soon apparent that this was to be a well-attended event. Once everyone was seated, the first presentation started on time at 1:00 pm. The first paper was presented by the IEEE Phoenix Chapter’s own chairman Harry Gaul, who presented a paper on “The Influence of Ground Plane Reflection on Antenna Calibration and Measurements”. This presentation started out with a riddle: Which configuration is likely to have a better chance of reception given a 2 km distance between antennas at 450 MHz with a height of 2 meters (assuming a direct line of sight): across a still lake; across a golf course with mounds; or would both scenarios be equal? Harry’s presentation provided the theory and details of performing antenna calibrations in both free space and ground plane configurations in accordance with standards such as ANSI C63.5 and SAE ARP958. The concept of Normalized Site Attenuation (NSA) was introduced as a means to derive the difference between free space and ground plane test configurations. Antenna range measurements were also discussed from the standpoint of how to include the effects of reflection from earth with finite conductivity. It was concluded that ground plane reflections can induce serious errors if not properly accounted for during antenna calibrations and measurements. The effects of specular ground plane reflections can easily be modeled with today’s sophisticated mathematical software and additional considerations should include mutual coupling and the effects of cables. By the way, the answer to the riddle is that the golf course is more likely to provide good reception because of the deep nulls that are possible from the lake. The second paper, entitled “Anechoic Chamber Solutions for Antenna Pattern Measurements (APM)”, was presented by Dr. Vince Rodriguez of ETS-Lindgren. This presentation introduced the attendees to antenna ranges, and concentrated on rectangular and tapered anechoic chambers for APM. Rectangular chambers tend to have less critical source placement, and are the ideal configuration for swept frequency measurements. Tapered chambers tend to be better for lower frequencies, but have potentially higher bore sight errors. Absorber technology, quiet zone levels, and far field requirements were discussed as well as the proper absorber treatment for both tapered and rectangular chambers. Large compact range chambers were also discussed. James Young of Rohde & Schwarz presented the final paper, entitled “Improving the Accuracy of EMI Emissions Testing.” This presentation discussed the advantages and disadvantages of using a spectrum analyzer versus an EMI receiver to make EMI measurements. Spectrum analyzers must be used carefully due to the possibility of reduced frequency accuracy over large frequency ranges. For example, a span of 970 MHz (30 MHz to 1 GHz) results in approximately 1 MHz frequency resolution if the spectrum analyzer has 1001 bins across its display. Given a 120 kHz CISPR bandwidth over this range, the bin size is larger than the bandwidth, and frequency resolution is lost. Additional concerns regarding EMI measurements with spectrum analyzers include less control of dwell time, potential 3 dB versus 6 dB resolution bandwidths, and less dynamic range and overload protection. However, the spectrum analyzer is a very versatile instrument, and may be used for EMI measurements as long as its limitations are well understood. The presentation suggested that a spectrum analyzer or test receiver may be used for initial scanning to make a frequency “hit-list” as well as for maximization, and that the test receiver is optimal for making final measurements. The presentation went on to review the issues of RF and IF overdrive as well as the problems and benefits of using low noise amplifiers for increased sensitivity. Once the presentations were complete, a reception was held with the speakers, including hands on demonstrations and a drawing for prizes. Congratulations to Dennis Kennedy for winning the iPod and David Lee for winning the 1GB memory stick. The IEEE Phoenix Chapter wishes to thank all of those who made the Tech Tour possible, including the sponsors: Rohde & Schwarz, ETS-Lindgren, and Conformity Magazine. We would like to thank all of those who participated in this very successful event, especially TMS Marketing! Information on future meetings is available on the Phoenix EMC Chapter Web site at

The recently formed Pittsburgh Chapter of the EMC Society held a special two-day inaugural meeting January 31, 2006 and February 1, 2006. The meeting venue was the Westinghouse Energy Center in Monroeville, Pennsylvania. Michael Oliver, IEEE EMC-S Chapter Chair, hosted the meeting along with Vice-Chair Harry Godlewski. The EMC-S Chapter would like to thank Kalyan Sen, PhD for his expert advice and continued Chapter coordination and support. The inaugural meeting started with a social prior to the technical presentation. We had the privilege of having Elya Joffe from K.T.M. Project Engineering, the VP for Member Services of the IEEE EMC Society, as our technical speaker, and Richard Ford from the US Navy, Washington DC as the “Chapter Angel” in attendance among the 40 plus attendees. Discussions on the first day of the inaugural meeting encompassed the role of “Chapter Angel” presented by Richard Ford. Next, a technical presentation was given by Elya Joffe on “Frequently Asked Questions About EMC.” Mr. Joffe’s presentation described issues relating to decoupling strategies, PCB layout, enclosure shielding, and ground loops. The second day of the inaugural meeting focused on two presentations by Elya Joffe. The first, “Path of Least Inductance Principal” described issues relating to frequency and single point or multi-point grounding, when to ground a shield at both ends or at only one, and how return current flows on a PCB not always taking the shortest path. Elya’s second presentation of the day, “Electrophobia or Why Are People Really Scared of EM Fields,” described the history of EMF usage, the evolution of EMR standards, from the turn of the 20th century to date, and the evolution of public response to EMF and its usage. The talk addressed this controversial issue from a user’s point of view concerning the sources of fear, facts, fallacies, and the risk in risk research. Each of the presentations was very well received by all. In addition, the attendees received handouts of the presentations. Many students from Geneva College attended. Matthew Kennedy, Geneva IEEE President stated, “Events like this one are a great opportunity for upperclassmen to meet professionals, and good for attracting underclassmen to the IEEE”. The future presentation schedule includes some great topics such as in May 2006: “EMC: An Overview” by Harry Godlewski, July 2006: “EMI for Working Engineers” and “The ‘Ground’ Myth” by Dr. Bruce Archambeault, September 2006: “The New EU EMC Directive” by Gary Fenical and October 2006: “Testing for EMC Compliance” by Ed Nakauchi.

The SCV Chapter was honored to have EMC-S Distinguished Lecturer, Dr. Ing. Heyno Garbe, University of Hanover, as a speaker for their April 3, 2006 meeting. The meeting kicked off with dinner, social time and announcements by the Chapter Chair, Hans Mellberg. A special announcement was given by Todd Robinson, the Publicity Chair for the 2006 IEEE International Symposium on EMC, who was on hand to invite SCV Chapter members to be in Portland 14-18 August 2006. Although the meeting was not held on the traditional second Tuesday of the month, there was a good turn out to hear Dr. Garbe’s interesting presentation on the “EMC Challenges of Local Area Networks.” His talk focused on first identifying typical EMC and EMC related problems with LANs, such as data symmetry and poor cable shielding practices. Second, Dr. Garbe outlined the application of good shielding and data symmetry practices. Ultimately, Dr. Garbe illustrated that good EMC practices in LAN cabling and installation translate into better LAN performance.

The Seattle EMC Chapter kicked off the New Year with a presentation on January 24 by Jim Skelly of Cybershield. The title was “Conductive Coatings in EMC Shielding Systems.” It was a very informative talk on the history of coatings and applications for various types of coatings with cost versus performance analysis. Several sample products were distributed to the audience. It was a good review for those who use plastics and still shield for EMC issues. The presentation also covered ROHS and WEEE issues related to the coating process. It was a pleasure having Mr. Skelly as a speaker; his enthusiasm for his work was truly infectious. The meeting was held at Arrow Electronics in Bellevue. In February, the Seattle EMC Chapter held a joint meeting with several Seattle Section Chapters, including the Microwave Theory and Techniques Society’s local Chapter. Seattle Section Secretary, Joe Decuir, a senior engineer with MCCI, a very energetic and capable speaker, presented an update on the topic of Ultra Wide Band (i.e. 500 MHz bandwidths) standards. Some of the material presented was updated just that morning of the meeting! The meeting was held at the University of Washington. In March, the Chapter was treated to a special meeting – at the new location of CKC Labs in Bothell, with an EMC Society Distinguished Lecturer, Dr. David Pommerenke of the University of Missouri at Rolla, as the speaker. Dr. Pommerenke spoke on “Advanced ESD and EMI Analysis Methods.” The attendees learned that there is no single method that allows identifying all the reasons for EMI and ESD problems. One needs to be aware of and have experience in a variety of methods and apply hopefully the most suitable method. The presentation showed different methods for EMI and ESD analysis, including PCB level scanning (ESD) and how this relates to IC level and system level test results. On EMI, Dr. Pommerenke noted that finding the sources and the antennas is usually not a problem, but understanding and quantifying the coupling path is sometimes close to impossible. He presented the use of port impedances and transfer functions for determining coupling paths and for the measurement of very hard to measure currents, for example, common mode current on a differential trace. All agreed it was a great presentation and all appreciated the hospitality of CKC Labs holding the meeting at their new facility.

Sendai (Japan)
During 2005, the Sendai Chapter held three technical meetings, two of which were the IEEE EMC-S Sendai Colloquium and one of which was the workshop of PLC (Power Line Communications). The first meeting in 2005 was held on June 26, with two lectures being presented. First, Professor Osamu Fujiwara of the Nagoya Institute of Technology spoke about “Static Electricity and EMC.” Dr. Fujiwara presented remarkable and excellent results of experimental and theoretical research work on ESD and EMC. Next, a talk entitled, “Measurements and Analyses of Switching Arc Discharge on Electric Contacts for Automobile Circuits” was given by Dr. Junya Sekikawa of Shizuoka University. Dr. Sekikawa showed some interesting results obtained in his experimental research on the discharge phenomena at the metal contacts of an electric switch. Interestingly, he displayed some movies of arc growing and dancing during the discharge between contacts. The PLC workshop was held on November 14 and 15 at Tohoku University. Eight specialists on this topic presented their latest research work relating to PLC technologies, and discussed the results of a special committee on PLC in Japan. This workshop was held in cooperation with the Japan Chapter of EMC-S. Many researchers and over 60 persons gathered and concentrated their attention on these presentations. The second colloquium in 2005 was held on December 26 and 27. Professor Osami Wada of Kyoto University gave a lecture entitled “EMC Design of Printed Circuit Boards.” This talk included his integrated research work on current design issues and forecasting for EMC technologies in the future. Four excellent presentations by EMC specialists from Japanese companies followed, showing their latest EMC research work including, “Near Field Measurement for EMC Countermeasure” by Dr. Satoshi Kazama (Taiyo Yuden Co., Ltd.), “EMI Countermeasure of a Micro-Processor-Power System Which Used a 3-Terminal Capacitor” by Mr. Hidetoshi Yamamoto (Murata Manufacturing Co., Ltd.), “Common Mode Filter for High Speed Differential Signal” by Mr. Masao Imamura (TDK Corporation) and “Novel Noise Solution for Digital Devices” by Mr. Hiroshi Ono (NEC Tokin Corporation).

February and March have been a very busy season for the Singapore EMC Chapter. To begin with, the Chapter hosted the 17th International Zurich Symposium on EMC in Singapore, from February 27 to March 3, 2006. The “EMC Zurich Singapore 2006” event was a great success with over 450 international delegates in attendance. On February 27, the Singapore Chapter organized a dialogue meeting between Andrew Drozd, the President of IEEE EMC Society, and Professor Todd Hubing, Past President of the IEEE EMC Society, and members of the Singapore Chapter. The meeting took place at the Singapore International Convention and Exhibition Center, where Dr. Drozd gave a “State of the EMC Society Message.” Professor Hubing then delivered a seminar entitled, “Effective Strategies for Printed Circuit Board Decoupling.” Over 70 EMC professionals attended the talks, including six Singapore Chapter Committee members, Li Erping (Chapter Chair), See Kye Yak (Chapter Deputy Chair), Yan Seow Chiang (Chapter Secretary), Ng Buck Chew (Chapter Committee member), Tim Foo (Chapter Treasurer), and Deng Junhong (Chapter Committee Member). Also in attendance were IEEE EMC Society Board members Mark Montrose, John Norgard, Lee Hill, and Francesca Maradei. On March 7, 2006, Dr. C. K. Chou, the Chief EME Scientist of Motorola USA gave a technical talk on “RF Exposure and Health: Research and Regulations” to over 50 participants. The meeting was held at the Singapore A-Star Institute of High Performance Computing.

SE Michigan
On March 2, 2006, the Southeast Michigan Chapter presented a free one-day workshop titled “Basic Antenna and Probe Use in EMC.” Presenters included Zhong Chen of ETS-Lindgren, Tom Holmes of Agilent Technologies, Candace Suriano of Suriano Solutions, and Paul Zdanowitz of Fair-Rite Products. The workshop featured hands on demonstrations, empirical data, and great information to allow attendees to better understand the magic and the theory of EMC. Over 80 people attended the workshop, despite the terrible weather, which had closed some roads due to ice and snow that day. Dr. Suriano has organized this popular workshop as part of the technical program at previous IEEE EMC Symposiums for several years now. This year, Chapter Officers encouraged Dr. Suriano to hold the workshop for her local Chapter! If you’ve missed this popular workshop, be sure to attend the next one, which will be held at the 2006 IEEE International Symposium on EMC in Portland, Oregon. See page 46 for more information.
