The 2021 IEEE Radio Frequency Integrated Circuits (RFIC) Symposium, is currently planned as a hybrid event with both in-person and virtual activities. In person events will be held at the Georgia World Congress Center, in Atlanta, GA starting on Sunday, June 6, 2021 and lasting through Tuesday, June 8, 2021. This will include a wide variety of workshops, technical sessions, panels, interactive demonstrations, and a technical exhibition. Remote attendees will likewise be provided a rich and interactive technical program. As in 2020, the 2021 RFIC Symposium continues with an expanded scope to include systems and applications for cutting-edge research in 5G, radar, imaging, biomedical, optoelectronic, and machine-learning areas. Also, a rich and diverse program for students will continue in 2021, including a best student paper contest, a virtual three-minute thesis (3MT) contest, a deeply-discounted student Superpass, and programs for both volunteers and Ph.D. students.
