Mindy Yao Receives IEEE AP-S Pre-Doctoral Research Grant
Undergraduate researcher Mindy Yao received the prestigious 2025 IEEE Antennas and Propagation Society (AP-S) Pre-Doctoral Research Grant. Mindy worked as researcher at the mmWave Antennas and Arrays Laboratory. She has made contributions to the mmWave robotic antenna measurement setup as well as spherical nearfield to farfield transformations. She graduated with a B.S. degree in Electrical Engineering from Georgia Institute of Technology in December 2025 and joined Skyworks as an RF Module Design Intern. Congratulations Mindy!
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). He is currently an Associate Editor of the IEEE Transactions on Antennas & Propagation. His research focuses on mmWave phased arrays, reconfigurable antennas, reflect-arrays, transmit-arrays, on-chip antennas, phase-change materials, non-reciprocal microwave devices, high-power arrays, and mmWave measurement techniques. He joined the School of ECE at Georgia Institute of Technology as an Assistant Professor in August 2021.
Ghalichechian Receives Roger Webb Junior Faculty Award
Prof. Ghalichechian receives the 2024 Roger Webb Junior Faculty Award from the School of Electrical and Computer Engineering. This award recognizes the most outstanding assistant professors and/or associate professors in ECE with less than 10 years since their initial faculty appointment.
