Sunny San Diego marked the first industry conference and exhibition that we have seen that was back to “normal.” With more than 9,200 registrants and 2,700 delegates, IEEE MTT-S IMS 2023 had an attendance and activity level that has not been seen since the pre-COVID days. The event took place June 11-16 with a technical program that had some 360 technical papers, presenting “the Coolest Ideas under the Sun” in the RF and microwave field, in addition to the industry exhibition with about 550 companies demonstrating their latest products and services. It was a great networking event with many re-connecting in person for the first time in a while.

IMG_5247.jpgIMS2023 introduced several innovations. The focus themes included:

  • Wireless Communications, including 6G developments, Wi-Fi, RF and microwave system-on-chip integration, massive MIMO systems and subsystems and more
  • Artificial Intelligence and Machine Learning (AI/ML) Technologies for Microwaves
  • Model-Based Systems Engineering, including Digital Twins
  • Space and Aerospace
  • Wireless Power Transfer
  • RF and Microwave Technology in Biomedical Applications.

Each theme had focused technical sessions, workshops, a keynote speaker, a panel session and a technical lecture. Additionally, there was a “Systems Pavilion” in the industry exhibition, showcasing wireless, with demos by the finalists in the ‘MTT-Sat Challenge.’ IMS2023 also featured the “Connected Futures Summit” co-sponsored by the IEEE Communications Society.

With a show as massive as IMS, it can be challenging to see everything the show has to offer. Whether you were unable to make the event, busy meeting with colleagues, participating in the technical program, or a culmination of all, you may not have had the time to walk through the exhibition as much as you'd like to. That's why Microwave Journal has put together this IMS2023 show wrap-up, in case you missed the best of IMS2023 exhibition.
