Sonny Lee Wins 3rd Place in Student Paper Competition at IEEE International Symposium on Phased Array Systems

Sonny’s paper, “Highly Integrated mmWave Antenna-on-Chip Arrays Using Substrate-Integrated Air Cavities,” won third place in the student paper competition at the IEEE International Symposium on Phased Array Systems (PAST). The paper presents the design, fabrication, and characterization of a 60 GHz beamforming array for 6G high data-rate wireless systems. The proposed silicon-based antenna offers the potential for future wireless system-on-a-chip (SoC) applications better equipped to handle high data throughput. Congratulations Sonny!

Sonny and Thomas Presented at IEEE Phased Array

Two Ph.D. students from the mmWave Antennas and Arrays Laboratory – Seung Yoon (Sonny) Lee and Thomas Williamson – presented their papers at the 2024 IEEE International Symposium on Phased Array Systems & Technology (PAST) held October 15-18 in Boston, MA. Sonny’s paper is titled “Highly Integrated mmWave Antenna-on-Chip Arrays Using Substrate-Integrated Air Cavities”. Tom’s paper is titled “A 10–50 GHz Ultrawideband Low Loss mmWave VO2 based Phase Shifter for Passive Scanning Arrays”.

Walter Disharoon Receives Herbert P. Haley Fellowship

Ph.D. student Walter Disharoon received the Herbert P. Haley Fellowship. Walter joined Georgia Tech as a Ph.D. student in 2021. He joined the mmWave antennas and arrays laboratory in Spring 2022. He won the fellowship for his continued research on VO2-based reconfigurable metasurfaces including a reconfigurable reflectarray and an energy selective surface.  Congratulations Walter!

Ghalichechian Promoted to Associate Professor

Dr. Nima Ghalichechian has been awarded promotion to the rank of Associate Professor with tenure in the School of Electrical and Computer Engineering in the College of Engineering at Georgia Institute of Technology.

Dr. Ghalichechian is the Director of the mmWave Antennas and Arrays Laboratory and Associate Director of the Georgia Electronic Design Center (GEDC).
