 ▲ Award achievements of Ph.D. students Seungwoo Bang and Byeongjin Kim

​Professor Jungsuek Oh’s research team from the Department of Electrical and Computer Engineering at Seoul National University has simultaneously produced winners for the Student Paper Award and the Travel Grant program at IEEE AP-S/URSI 2026, a premier international conference in the field of antennas and propagation. The IEEE AP-S/URSI is a leading global academic event where the latest research on antennas and radio wave propagation is presented.

​Seungwoo Bang, an M.S.-Ph.D. integrated led by Professor Oh, won 3rd place in the Student Paper Competition. Out of 10 Finalists worldwide, Bang was selected as one of the top five award winners after an intensive on-site presentation and Q&A evaluation.

The award-winning research focuses on a liquid crystal-based RIS (Reconfigurable Intelligent Surface) technology. Instead of connecting wires individually to 10,000 radio wave elements, it controls the array using just 200 common lines (100 horizontal and 100 vertical). The team proposed a method to transmit radio waves not only horizontally and vertically but also diagonally, even within this highly simplified structure 

RIS is a technology that essentially allows walls or windows to act as "smart mirrors" for radio waves. It can bend and redirect radio waves to areas with weak Wi-Fi signals in a house, underground parking lots, or around elevators. In the future, this technology is expected to be widely utilized in smart buildings, smart factories, autonomous driving, and 6G communications.

​Byeongjin Kim, another M.S.-Ph.D. integrated candidate under the guidance of Professor Oh, was selected as a recipient of the 2026 IEEE AP-S C. J. Reddy Travel Grant. This program evaluates first-author papers and research proposals to support up to 10 outstanding graduate students worldwide, with Kim securing his place this year. 

​The achievements of both students serve as an international recognition of Professor Oh’s research team and their exceptional capabilities in the fields of next-generation antennas, RIS, metasurfaces, and 6G wireless communication research.
