Four earthquakes and a tsunami warning not withstanding, the IMS 2005 Symposium and Exhibition in Long Beach, CA turned out to be a huge success. Cool ocean breezes and hazy days were the norm outside, while crowded technical sessions and a busy show floor were the norm inside the spacious Long Beach Convention Center (LBCC). The MTT-S International Microwave Symposium was held June 12 to 17 with an overall attendance topping 11,000. It is safe to say everyone had a good time.
Charlie Jackson, the General Chairman, and his superb team of volunteers did a great job of organizing and implementing this year’s Microwave Week activities and the City of Long Beach played happy host to all of the attendees. The roomy Long Beach Convention Center was a short walk to the waterfront and its renowned Aquarium of the Pacific, while across the bay the elegant Queen Mary played host to many of our visitors.
In addition to the MTT-S International Microwave Symposium and Exhibition, the 2005 Radio Frequency Integrated Circuits (RFIC) Symposium and the 65th ARFTG Measurement Conference held their events during the week. The RFIC Symposium was chaired by Joseph Staudinger and held from Sunday through Tuesday; the ARFTG Microwave Measurement Conference was chaired by Tom Ruttan and was held on Friday. All three events were a solid success and their respective organizing teams are to be congratulated.
The Technical Program
The Technical Program kicked off with two inspiring Plenary Session keynote addresses. “Digitally Assisted Analog Design for Wireless SoCs and Its Future” was presented by Dr. Teresa Meng, professor of electrical engineering at Stanford University, and Mr. Ziqiang Hou, professor at the Institute of Acoustics China Academy of Science, presented “3G and Mobile Broadband Wireless Access.”
In recent years the MTT-S technical program has become bigger and bigger and this year was no exception. There were 344 oral presentations and 149 interactive forums held under the guidance of Dave Rutledge, this year’s TPC Chair, and Co-chairs Mike DeLisio and Bob York. In all, 2856 delegates attended the 87 technical program sessions and 38 workshops. The workshops this year were organized by Ethan Wang and the special sessions were organized by Alina Moussessian. In addition, there were lunch sessions organized by Emilio Sovero, and 20 student papers were nominated for the Student Competition.
The RFIC Symposium Reception in the Grand Ballroom of the Long Beach Convention Center Sunday evening kicked off the week’s social program, followed Monday evening by the Microwave Journal/MTT-S Reception held at the Aquarium of the Pacific. Other events included the IEEE MTT Women in Engineering Reception and the Ham Radio Social, both held in the Hyatt Hotel. Wednesday was the traditional Industry-hosted Cocktail Reception followed by the IEEE MTT-S Awards Banquet. This year our own Harlan Howe, Jr. received the well-deserved 2005 Distinguished Service Award in recognition of his significant contributions and outstanding service to the MTT-S and the microwave profession. We here at Microwave Journal are very proud of Harlan’s achievements over the years. The week’s social program also included the IEEE MTT-S Student Awards luncheon and the Technical Attendees Breakfast in the LBCC.
