Master's student Suyeon Kim (Division of Electronics and Information Engineering, Graduate School; advisor Professor Yongchae Jeong) received the Outstanding Paper Award at the recently held '2026 Korean Electromagnetics Society Winter General Conference'.

The Korean Electromagnetics Society is a leading society in the fields of electromagnetics and information and communications in Korea, and has led development across academia, research, and industry. Held under the catchphrase 'A View of the Quantum, a Gateway to Space: Electromagnetic Technologies', this conference served as a forum for scholarly exchange to survey the current and future state of electromagnetic technology, from precise electromagnetic measurements and quantum technologies in the microscopic world to macroscopic applications encompassing satellite and space systems.

Suyeon Kim gave an oral presentation titled 'Branch-Line Hybrid Coupler Based on Complex Termination Impedance Using Open/Short Stubs'.

This study departs from conventional circuit design methods that used only 50-ohm (Ω) termination impedances by enabling the use of complex termination impedances. It demonstrated that circuit size can be significantly reduced while improving performance. The proposed approach can be widely applied to RF circuits used in mobile, satellite, and military communications.

Suyeon Kim said, 'I hope to contribute to the advancement of wireless communication systems through follow-up research applying this to actual RF circuits.'

This research was conducted with support from the Regional Intelligence Innovation Talent Development Project, the University Research Center Support Program for Science and Engineering, and the BK21 Project Division's BK21 JIANT-IT Human Resources Development Project.
