Dongseop Lee (Integrated M.S.–Ph.D. student) from the Department of Electrical Engineering at POSTECH (advisor: Prof. Wonbin Hong) has been selected for the 2025 POSTECH Alchemist Program, a university-wide initiative supporting high-risk, high-impact research projects. The program encourages innovative and challenging research across all disciplines at POSTECH, including mechanical engineering, electrical engineering, chemistry, life sciences, and physics.

Lee’s project was selected in the “Disruptive Technology” category. This year, a total of 60 proposals were submitted to the program, and only 15 projects were selected after a rigorous evaluation based on innovation, research capability, and potential industrial impact. Notably, Lee’s project was the only one selected from the Department of Electrical Engineering, highlighting the significance of the achievement.

The selected project, titled “Integrated Radar Sensing and Communication (ISAC) System for 5G/6G Using Antenna-on-Display Technology,” proposes a novel system that integrates a Traveling-Wave Antenna-on-Display (TWAoD) structure into the transparent region of a display panel. By enabling two-dimensional beam scanning in the millimeter-wave band, the system demonstrates that a single ultra-thin transparent antenna can simultaneously perform radar sensing and high-speed wireless communication.

This approach fundamentally addresses the space constraints faced by conventional ISAC systems and presents a new paradigm for next-generation applications, including automotive systems, mobile devices, and satellite communications. Compared with previously reported studies, the proposed solution offers distinctive performance and innovation, suggesting strong potential for future 6G technologies and integrated sensing and communication systems.
