Military Microwaves Supplement
Recent Advances in Radar Technology
Using Calibration to Optimize Performance in Crucial Measurements
IMS 2008 represents the return of the International Microwave Symposium to the east coast after five years on the west coast and beyond (with Hawaii last year). While everyone had Microwaves on their mind, I was hoping that the attendance and participation would come back strong after a below average year in 2007. This year’s show did bounce back with about 9000 total attendees and about 2500 technical session attendees although this was well below the record numbers set a several years ago in San Francisco. I expect Boston next year to set a new record (or at least come close) because of its convenient location for many RF and microwave companies. However, the buzz around the symposium this year about locations was a return to Hawaii in 2016.
The weather was very nice (a little hot and humid at the beginning of the week) and the Georgia World Congress Center was extremely comfortable and convenient with all of the meeting rooms and exhibition very close to each other. The IMS, RFIC and ARFTG organizations worked very hard to put together a strong technical program and made it convenient for everyone who attended.
Congratulations to the general chairs, Joy Laskar – 2008 International Microwave Symposium General Chair, Jenshan Lin - 2008 RFIC General Chair, and Nick Ridler – 71st ARFTG Conference Chair and all of the volunteers who helped them make this a very successful symposium. The technical program for each conference was very strong thanks to the hard work of the technical chairs Manos Tentzeris – IMS, Tina Quach and Yann Deval – RFIC, Roger Pollard – ARFTG and all those who helped them.
The Technical Program
The Plenary session on Tuesday kicked off the sessions with a very entertaining tornado themed video including funny scenes from the Wizard of Oz mixed in with actual photos of the severe damage in Atlanta after the storm. Everyone should be congratulated for working long hours after the tornado to get the convention center and the surrounding community back together in time for the symposium. There were still many broken and taped windows on the buildings, but there were no residual issues that affected the symposium. The two Plenary speakers were Joseph H. Taylor who talked about “Symbiotic Relationships in Technology and Basic Science” and Mike Farmwald who’s talk was entitled “What Should ‘Open Access’ Wireless Really Mean? – A Modest Proposal”.
This year, over 240 reviewers on the Technical Program committee were responsible for selecting the 279 papers for oral presentation and the 132 papers for the interactive forums. Choosing from the 762 submitted papers, the quality of the technical content was exceptional. Organizers also rearranged the schedules of the regular sessions so that the IMS attendees could have more flexibility to attend the RFIC sessions.
The panel sessions focused on automotive radar, multi-gigabit wireless, wireless medical, system/service engineering and cognitive radio. An evening Rump Session featured a talk by Joseph H. Taylor, entitled “The Discovery of Gravity Waves Amidst the Noise.” Thirty-eight workshops, four of which were jointly organized by IMS/RFIC and one organized by IMS/ARFTG, took place on Sunday, Monday and Friday. This year’s IMS also included a student paper competition as well as three design competitions. The student participation seemed strong with Georgia Tech leading the way.
The Social Program
The RFIC reception on Sunday night and IMS reception on Monday night kicked off the social activities. Tuesday night included the Women in Microwaves reception along with a Student reception. And Wednesday started off with the industry hosted cocktail reception followed by the MTT-S Awards Banquet. In addition, there were several Guest Program tours of attractions in the area.
The Industry Exhibition
Over 450 companies displayed their products and capabilities over the three day exhibition which was up significantly from last year. In general, most companies said the traffic was fairly robust (but not overwhelming) and the quality of inquiries was good. There was an impressive amount of new products and services introduced at the show. The Microwave Journal published an Online Show Daily that featured live video interviews from the show floor, virtual booths, podcasts on what to see and do, a Microwave Blog with real time updates by our editors and daily news and product announcements. The coverage will continue until June 27 and can be found on our home page. Please visit our Blog to see our coverage and comment on any of the events or sessions at www.microwavejournal.blogspot.com.
There seemed to be quite a bit of buzz about the recent acquisitions like Triquint acquiring WJ Communications, Cobham acquiring M/A-COM, Ansys acquiring Ansoft and even the previously announced additions to RFMD of Filtronics and Sierenza. I think GaN is starting to come into it own with many companies announcing new products and even foundry services (Triquint and Cree).
There was an impressive line up of new products from some of the leading companies in the microwave industry. The IMS 2008 Industry Exhibition highlighted several key introductions from exhibitors around the globe.
