IMS 2006: Another Record Breaker
Ten years ago IMS 1996 set records as the largest IMS Symposium and Exhibition to date. San Francisco once again proved a great draw for our industry and its many engineers. IMS 2006 was indeed another record breaker, with over 12,000 total attendees and almost 3000 conference delegates registered. In addition, the characteristic San Francisco fog was a no-show. All in all, Microwave Week was a huge success and a rewarding week for all that attended.
Much of the credit for that success goes to this year’s general chairman, John Barr, and his very capable staff, including Elsie Cabrera and the staff from IEEE headquarters in New Jersey. They are to be congratulated for their dedicated efforts and attention to detail that makes this event such a well run and rewarding experience. Thanks must also go to the Moscone Center and SFCVB staffs. They and their superb facility were gracious hosts and enabled our week’s program to run smooth and efficient.
Thanks also to the general chairman of the 2006 RFIC Symposium, Stefan Heinen, and to Ken Wong, the conference chair of the 66th ARFTG Measurement Conference, and their able staffs. Both the RFIC and ARFTG conferences were equally successful and well attended.
The Technical Program
This year’s technical program was comprised of 246 oral presentations and 166 interactive forums. There were 55 separate program sessions and 42 workshops, with five panel sessions and an interesting rump session presentation by James Rautio celebrating the 175th anniversary of the birth of James Clerk Maxwell, attended by 600 individuals.
The program kicked off with two inspiring Plenary Session talks: “WiMAX and the Future of Mobile Wireless Broadband” by Ron Resnick, president and chairman of the WiMAX Forum; and Professor Richard White of the University of California at Berkeley, who spoke of “Nanotechnology: Hype or New Horizons.”
As mentioned before, there were just under 3000 registered delegates attending over 1000 various technical presentations. The IMS Technical Program was co-chaired by APS (Paul) Khanna and Roger D. Pollard. By all accounts this year’s comprehensive technical program was the most well attended and successful of any to date and remains the backbone of Microwave Week.
The Social Program
Kicking off the social side of the week was the RFIC Symposium Reception Sunday evening at the Moscone Convention Center Esplanade Ballroom and the traditional Microwave Journal / MTT-S Reception Monday evening, held this year outside in the Yerba Buena Gardens on top of the convention center’s south side. An earlier threat of rain gave way to an absolutely beautiful San Francisco evening and a good time was had by all.
Other prominent social gatherings included the IEEE MTT Women in Engineering Reception, the Ham Radio Social and the Student Reception, all held at the Marriott hotel. A reception was held prior to the Maxwell Rump Session, also at the Marriott.
Wednesday evening was the traditional Industry-hosted Cocktail Reception and the IEEE MTT-S Awards Banquet. Among the individuals recognized for their outstanding contributions were Peter Staecker, who received Honorary ADCOM Life Member Recognition for his continuing leadership in society affairs, and Roger Pollard, who received the 2006 Distinguished Service Award for his significant and outstanding contributions to MTT-S and the microwave profession. Other awards included Eikichi Yamashita, the 2006 Microwave Career Award, Wolfgang Hoefer and Peter Russer, the 2006 Distinguished Educator Award, Peter R. Herczfeld, the 2006 Microwave Pioneer Award, Marian W. Pospieszalski, the 2006 Microwave Application Award, Ian Gresham and Emmanouil Tentzeris, the 2006 Outstanding Young Engineer Award, Timothy T. Lee, the N. Walter Cox Award, and Joseph A. Hagerty, Florian Helmbrecht, William McCalpin, Regan A. Zane and Zoya Popovic, the 2006 Microwave Prize.
For those attendees and their families that wished to see some of the area’s better known tourist attractions, there were scheduled trips to Muir Woods, Alcatraz, Fisherman’s Wharf, Chinatown, Golden Gate Park and a San Francisco city tour, as well as a tour to the Carmel, Monterey area.

Hawaii in 2007
Many of you have expressed concerns about Honolulu as the site of IMS 2007. If you attended the exhibitor’s breakfast on the last day of this year’s show you are aware that many of the concerns are either not well founded or being addressed by the IMS 2007 chairman and his committee, and the Horizon House and Champion teams. Although travel and shipping costs are going to be somewhat higher for some, there are offsetting benefits in having this great symposium on the doorstep of Asia and its rapidly expanding marketplace. Much of today’s RF and microwave technology is generated and utilized in Asia, and many of the industry’s talented engineers reside in this region of the world. IMS 2007 will be an opportunity to more fully engage that segment of our industry in their backyard, so to speak. The Hawaii Convention Center staff and their facility are one of the best we have encountered and will be an excellent host to us. In addition, the hotel accommodations are superb and reasonably priced. For those of you that have never been to Hawaii, it’s an opportunity to see a truly unique part of the world. For those that have been there, you know there is nothing to compare to the Hawaiian hospitality. It’s going to be a great time and a very successful symposium and exhibition. Don’t miss it. Aloha!
