EMC Personality Profiles

Congratulations to the 2008 IEEE EMC Fellows

This year, three of our members that were evaluated by the EMC Society Fellow Evaluation Committee were elected to the IEEE Fellow Grade. In order to quality for election to the Fellow Grade, a member must have made a significant contribution to their field of endeavor.
I would like to offer my congratulations to our three new Fellows: Dr. D. V. Giri, Dr. Lothar O. Hoeft, and Dr. Erping Li for being elected to the Fellow Grade. These three new Fellows are our EMC Personality Profiles for this issue of the EMC Newsletter.
Dr. D. V. Giri was elected to the Fellow Grade as a Research Engineer/ Scientist “for contributions to the understanding and analysis of intense electromagnetic environments interacting with complex electronic systems.” A complete description of his academic training and work experience may be seen at his website: www.dvgiri.com
He obtained the B.Sc. from Mysore University, India in 1964, the B.E. and M.E. degrees from the Indian Institute of Science in 1967 and 1969, the M.S. and Ph.D. degrees from Harvard University in 1973 and 1975, and a Certificate for the Harvard Introduction to Business Program in 1981.

Dr. D. V. Giri has over 30 years of work experience in the general field of electromagnetic theory and its applications in NEMP (Nuclear Electromagnetic Pulse), HPM (High-Power Microwaves), Lightning, and UWB (Ultra Wideband). Dr. Giri has made significant technical contributions to the understanding and mitigation of the high power microwave threat to electronic circuits, equipments and systems.
He taught graduate and undergraduate courses in the Department of Electrical Engineering and Computer Science at the University of California, Berkeley campus. He is also an Adjunct Professor in the Department of Electrical and Computer Engineering, University of New Mexico, Albuquerque, New Mexico.
Since 1984, he has been a self-employed consultant doing business as Pro-Tech, in Alamo, California, performing R&D work for the U.S. Government and industry.
From May 1978 to September 1984, he was a staff scientist at LuTech, Inc., in Berkeley, California. Prior to his association with LuTech, Inc., Dr. Giri was a Research Associate for the National Research Council at the Air Force Research Laboratory (AFRL), Kirtland AFB, New Mexico, where he conducted research in EMP and other aspects of electromagnetic theory.
Dr. Giri is a Charter Member of the Electromagnetics Society, and Associate Member of Commission B, URSI and Vice-Chairman of Commission E, URSI. He has served on the editorial board of the Journal of Electromagnetics, published by the Electromagnetics Society. He has also served as an Associate Editor for the IEEE Transactions on Electromagnetic Compatibility. The awards committee of Summa Foundation elected him to the grade of Fellow in 1994 for his contributions to EMP simulator design and HPM antenna design.
He has coauthored a book titled High-Power Microwave Systems and Effects published by Taylor and Francis in 1994. Harvard University Press has published his second book titled High-Power Electromagnetic Radiators: Nonlethal Weapons and Other Applications in 2004. He has also published over 100 papers and reports.

Dr. Lothar (Bud) O. Hoeft was elected to the Fellow Grade as an Applications Engineer/Practitioner “for contributions in demonstrating surface wave transfer impedances to be an intrinsic electromagnetic shielding characteristic.”
Dr. Hoeft received a Bachelors Degree from the University of Wisconsin in 1953, a Masters Degree from the University of Wisconsin in 1954, and a Ph.D. Degree from the Pennsylvania State University in 1961.
He is currently working as a private consultant in the area of electromagnetic effects. He was a Senior Scientist with BDM International from 1979 to 1994. From 1975 to 1978, he was the USAF Weapons Laboratory Scientific and Technical Coordinator of the Chief Scientist’s Office. From 1971 to 1975, he was with the Air Force European Office Physical Science Program Office of Aerospace Research and Development-USAF Weapons Laboratory Chief, Simulation and Laboratory Support.
Dr. Hoeft used the surface transfer impedance (Zt), which is an intrinsic property of electromagnetic shields, to characterize the behavior of a wide range of electromagnetic shielding problems and to design electromagnetic shields for a wide range of applications and shielding materials. These include the shielding performance of cables, ferrite and non-ferrite loaded conduits, cableways, metallized plastic tapes, knitted wire mesh cable shields and connectors, and a wide range of equipment boxes and racks. He also made significant advances in the “art” of performing Zt measurements at frequencies as high as 1 GHz.
Dr. Hoeft’s work has influenced the development of more effective cable and connector shielding and has also influenced the manner in which the Air Force monitors the shielding of aircraft.
He has published a number of technical papers related to his work. He has been active in the IEEE EMC Society as a Distinguished Lecturer and as a member of the Shielding Artifact Working Group (TC-4).
In 2005, Dr. Hoeft was awarded Honorary Life Membership in the IEEE EMC Society “for over two decades of electrical effects analysis, experimentation and reporting particularly in connection to cable and connector shielding, as well as professional support of various EMC Society Committees and as an EMC Society Distinguished Lecturer.”

Dr. Erping Li was elected to the Fellow Grade as a Research Engineer/ Scientist “for contributions to electromagnetic modeling and simulation with applications in high speed electronics, EMC/EMI and signal integrity.”
Dr. Li received a Bachelors Degree from Hebeai University of Technology in 1983, a Masters Degree in Electrical Engineering from Xian Jiao Tong University in 1986, and a Ph.D. in Electrical Engineering from Sheffield Hallam University in 1992.
Since 2003, Dr. Li has worked for the Electromagnetic and Electronics System Department, Institute for High Performance Computing, in Singapore as a Senior Scientist and Senior R&D Manager. He has also worked at several universities.
Dr. Li has made outstanding contributions to the field of computational electromagnetics (EM) that resulted in novel simulation techniques with applications in EMC/EMI, high speed electronic interconnects and signal integrity. He developed practical engineering solutions by finding creative and innovative ways to reduce the computational modeling effort. His groundbreaking algorithms have been cast into software packages used by industry in the analysis and design of complex high-speed electronic packaging considering power and signal integrity, and solving general EMI/EMC problems. His work has significantly advanced the understanding and the state-of-the-art in the modeling and design of mixed-signal integrated circuits, their packaging, and the hybridization of EM algorithms for efficient simulation of EMC problems in large-scale systems.
His achievements include:
• Development of a unique top-down approach for accurate and efficient modeling of electromagnetic susceptibility of electronic systems
• Introduction of a hybrid macro model FDTD-mixed potential integral equation method for EMI and signal integrity problems in multilayer high-density PCB packages
• Establishment of solution methods for large-scale and macroscopic problems by developing an efficient hybrid fast multipole technique coupled with the Finite Element Method and ray-tracing method
• Spearheaded breakthrough solutions for testing techniques in reverberation chambers, such as moveable directly energized electronic stirrers instead of conventional stirring techniques.
• Authored and co-authored over 120 technical papers for international journals and conferences. He holds one US and one Singapore patent. Three more patent applications are filed with the US patent office.
In addition to his technical achievements, Dr. Li has made other contributions to his profession. He was co-founder of the IEEE EMC Singapore Chapter in 2001. He served as Chapter Vice-Chair from 2001 to 2004 and Chapter Chair from 2005 to 2006. Under his leadership, the Chapter received the Most Improved Chapter Award in 2005. He was the organizer and President of the 17th EMC Zurich Symposium in Singapore in 2006. Dr. Li has been involved in starting a major EMC Symposium in the Asia-Pacific region in collaboration with EMC Zurich. He has been involved in organizing 12 international conferences and served as technical program chair, session chair and technical program committee member on numerous international conferences and workshops. Dr. Li received the IEEE EMC Society Technical Achievement Award in 2006. EMC
