15th International Zurich Symposium & Technical Exhibition on Electromagnetic Compatibility

Symposium President Prof. R. Vahldieck, ETH Zurich, addressing the audience during the opening ceremony.

The 15th International Zurich Symposium & Technical Exhibition on Electromagnetic Compatibility (EMC Zurich '03) was again held at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, February 18-20, 2003. The Symposium took place in the main building of the Swiss Federal Institute of Technology, which offered an impressive surrounding, convenient conference facilities and easy access to the city of Zurich. The event was jointly organized by the Communications Technology Laboratory and the Laboratory for Electromagnetic Fields and Microwave Electronics both of the ETH Zurich under the sponsorship of the SEV Association for Electrical Engineering, Power and Information Technologies. The more than 475 participants from 41 countries and the many national and international cooperating institutions such as the IEEE EMC Society, URSI, the International Telecommunications Union (ITU), the IEE as well as others (EBU, IEICU, VDE, SEP, ÖVE, SESKO, AEI, and the German Association for EMC-Technology (DEMVT)) made this a truly international event.

Professor Ruediger Vahldieck, Symposium President, chaired the opening ceremony on Tuesday morning. At the occasion of this 15th anniversary of EMC Zurich, Professor Vahldieck gave a brief review of its history. He honored Professor Thomas Dvorak who initiated EMC Zurich back in 1975 and is still its Honorary Chairman today. He then thanked Dr. Gabriel Meyer, who has decided to step down as conference chairman, for his many years of service and he emphasized that without Gabriel Meyer's dedicated effort, EMC Zurich would not be what it is today. In the following comments, Vice-President for Research (ETH), Professor U. Suter, Professor Todd Hubing and Dr. K.A. Hughes addressed the audience on behalf of the ETH administration, the IEEE EMC Society and the ITU-R in Geneva, respectively. The highlight of the opening ceremony was the keynote speech given by Dr. M. Repacholi from the World Health Organization (WHO), who spoke on "What Are the Health Effects of EMF and What To Do About Them."

Despite the difficult economical environment, paper submissions were at an almost normal level of 187. From those, 131 contributions were accepted and presented in 19 sessions covering a broad range of areas in the field of electromagnetic compatibility. In addition, the traditional pre-program one day before the opening of the symposium offered tutorials that were meant to be a primer for important upcoming issues in EMC. Tutorials were held on Modeling and Simulation of Electromagnetic Fields, Optimization Problems arising in EMC and EMV, Packaging Issues in High-Speed Circuits and The Application of Reciprocity Theorems in EMC Measurements. All four tutorials showed a high attendance rate underlining their importance to the EMC community. Parallel to the session, four workshops were held on Quantitative Data Comparison, Power Line Communications, Emission Measurements with Alternative Methods and GEMCAR European Project. Despite their tight scheduling all four topics drew large audiences and at times intense discussions evolved. The Industrial Forum took place on Thursday and was intended to give the EMC industry a platform to present not so scientific issues. A total of seven contributions were presented on such diverse topics as Comparison of EMC Test Laboratories, Ergonomic Manuals for Product Safety and Quality, Comparison of Immunity and Emission Measurements in Reverb Chambers, and Analysis of Finnish EMC Market Surveillance and Suggestions for Development.

The papers in the 19 sessions covered a wide variety of EMC issues. The technical program committee (TPC), chaired by Dr. Fred Tesche, as well as all the reviewers did a great job in selecting the best papers and grouping them as best as possible into the appropriate sessions. Besides the more traditional EMC topics, papers on test chambers, EMC innovation and automotive EMC attracted large audiences. It is interesting to note that numerical modeling of electromagnetic fields is increasingly becoming a central tool in many areas of EMC. Besides the tutorial on Modeling and Simulation of Electromagnetic Fields, one full session was devoted to EMC Modeling. The computation of electromagnetic fields was also a central topic in the sessions on Signal Integrity and CAD modeling, Test Chambers, Large Chip and Package EMC Modeling and Automotive EMC. The complexity of modern EMC structures makes model order reduction techniques an important topic in EMC simulation. Without model order reduction techniques the computational space for many EMC problems will soon become too large for main frames, not to mention workstation computers. It is therefore no surprise that the first place in the student paper competition went to the author of one of the initial papers on this topic: G. Steinmair from BMW and his co-authors H. Katzier, R. Weigel, and M. Troescher for the paper "Switching Noise and Ground Bounce Simulation on Packages and on PCBs Using PEEC and Model Order Reduction Techniques". Ch. Bruns from the ETH won the second place for his paper on "Three-dimensional Method of Moments Simulation of a Reverberation Chamber in the Frequency Domain". The third place went to M. Sabielny and H.-D. Bruens, TU Hamburg-Harburg, for the paper "Practical Aspects of the Physical Optics - Moment Method Hybrid Method". The prize money was 1000 CHF, 750 CHF and 500 CHF, respectively. For the student paper competition, a total of 14 papers were submitted. Of those, the Technical Program Committee selected the three best. A final presentation was held during the conference in front of a jury consisting of Professor Fred Tesche, Professor Marcello D'Amore, Dr. Gabriel Meyer, Professor P. Degauque and Professor K.-H. Gonschorek. The jury decided the winners.
The exhibition this year was not as large as in previous years. With only 31 exhibitors, this presents a problem that needs to be addressed if EMC Zurich wants to maintain the exhibition as a link between the ivory tower and the real world. Although the economic climate has much to do with this years' low attendance rate by companies, new ideas are welcome to attract larger exhibitor numbers in the future, and the new management committee of EMC Zurich '05 is already actively working to generate these ideas.
The social highlight of EMC Zurich was certainly the Symposium Banquet in the Grand Hotel Dolder with entertainment, good food and wine. The grand ambience of this fine Hotel always assures a memorable event that, at the same time, also marks the symposium midterm. On Thursday, the last day of the Symposium, all authors were invited for lunch and received a generous present in the form of an optical wireless mouse from Logitech. A rich social program for spouses and guests was also available every day during the symposium ranging from a visit to the Abbey-District (UNESCO world heritage site) and Chocolate-Land to the Engelberg Monastery cheese factory and Lake Luzern. On Friday after the Symposium, groups visited the Logitec development laboratories in Romanel-sur-Morges and EM Microelectronics, a Swatch Group Company in Marin.
Although the attendance rate of EMC Zurich '03 was down from previous years, it was an overall success with many excellent presentations, many interesting stories told and many interesting ideas exchanged. It is now time to look forward to EMC Zurich '05 which will take place during the year in which the Swiss Federal Institute of Technology celebrates its 150th anniversary. This anniversary will be celebrated over the entire year of 2005 with numerous events organized by the different departments of the ETH. EMC Zurich '05 will be the first event in the week of 16-20 February 2005. We promise you a special week full of EMC activities. EMC
