Do-Won Lee (PhD Candidate) Wins “Outstanding Oral Presentation Award” at the Korean Physical Society Conference

Do-Won Lee, a PhD candidate in the Department of Electrical Engineering at POSTECH (advisor: Professor Moon-Joo Lee), received the “Outstanding Oral Presentation Award” at the 2023 Spring Meeting of the Korean Physical Society. His presentation, titled “Real-time Monitoring of the Atomic Motion Trapped Inside a High-Finesse Optical Resonator,” was highly recognized for its excellence.

The conference covers a wide range of research topics, including semiconductor physics, electronic physics, optics, quantum electronics, and quantum information. In their presentation, Do-Won Lee and Professor Moon-Joo Lee’s research team showcased their successful trapping of neutral atom qubits inside a high-finesse optical resonator and their ability to monitor the motion of the trapped atoms in real-time.

Building on this achievement, the research team is focusing on the development of cavity-based quantum networks and large-scale quantum computers.

Beom-Hyun Kim and Dong-Seob Lee (Integrated PhD Students) Win “1st Prize Best Conference Paper Award” at 2023 IEEE iWAT

POSTECH Electrical Engineering integrated PhD students Beom-Hyun Kim and Dong-Seob Lee, under the guidance of Professor Won-Bin Hong, received the prestigious “1st Prize Best Conference Paper Award” at the 2023 IEEE International Workshop on Antenna Technology (iWAT).

The IEEE iWAT, organized by the IEEE Antennas and Propagation Society (IEEE AP-S), is a globally renowned conference in the field of antenna technology. It covers topics such as antenna design, advanced electromagnetic materials, compact antennas, medical antennas, mm-wave and THz technologies, and metamaterials. This year’s conference was held in Aalborg, Denmark. Notably, alongside Myung-Jin Hwang (Master’s student), who secured the “2nd Prize Best Conference Paper Award,” this marks the first time in the history of iWAT that a single research group has won both first and second prizes in different award categories.

At the conference, the authors presented their paper titled “mmWave Mobile Devices with Reconfigurable Broadside and Endfire Radiation using Shared Aperture Antenna-on-Display and Antenna-in-Package.” The research introduces a novel technique that combines Antenna-on-Display and Antenna-in-Package technologies into a shared-aperture structure. This innovative approach achieves compact packaging within mobile devices while maximizing coverage efficiency in the mmWave band. The integration and experimental validation of the technology with commercial mmWave devices further demonstrated its practical feasibility.

The study was highly praised for its originality, innovation, significance to the antenna and propagation community, potential impact, and technical excellence, earning it the top honor at the conference.

POSTECH Electrical Engineering Students Win “2nd Prize Best Conference Paper Award” at 2023 IEEE iWAT

POSTECH Electrical Engineering students Myung-Jin Hwang (Master’s student), Young-No Yoon, Chung-Ah Lee, Dae-Hyun Kim, and Dong-Geun Ahn, under the guidance of Professor Won-Bin Hong, received the “2nd Prize Best Conference Paper Award” at the 2023 IEEE International Workshop on Antenna Technology (iWAT).

The IEEE iWAT, organized by the IEEE Antennas and Propagation Society (IEEE AP-S), is a leading international conference that showcases cutting-edge advancements in antenna design, advanced electromagnetic materials, compact antennas, medical antennas, mm-wave and THz technologies, and metamaterials. This year, the conference was held in Aalborg, Denmark. Among the eight finalists in the Best Conference Paper Competition, the authors secured second place after a rigorous evaluation process. Remarkably, along with Beom-Hyun Kim (Integrated PhD Student), who won the “1st Prize Best Student Paper Award,” this marks the first time in history that a single research group has achieved both first and second places in different award categories.

At the conference, the authors presented their paper titled “Wireless Channel-Adaptive Sensor-Integrated Reconfigurable Intelligent Surface Based on Deep Neural Network.” The study proposed the first-ever sensor-integrated, actively controllable intelligent surface combined with deep learning technology, demonstrating the technology using a commercial mmWave device. The paper was highly praised for its originality, innovation, significance to the antenna and propagation community, potential impact, and technical excellence, leading to its recognition as an outstanding conference paper.

POSTECH PhD Student Receives Honorable Mention at IEEE AP-S/URSI 2023

POSTECH Electrical Engineering PhD candidate Dae-Hyun Kim (advisor: Professor Won-Bin Hong) has received an “Honorable Mention” in the Student Paper Competition at the 2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (IEEE AP-S/URSI). His paper, titled “Dual-polarized Metasurface Unit Cell using a sub-10-μm Thin Liquid Crystal Layer at 38 GHz,” was recognized for its excellence in innovation and academic contribution.

The research proposes a metasurface structure capable of beamforming by utilizing an ultra-thin liquid crystal layer with a thickness significantly smaller than the wavelength, addressing one of the major limitations of liquid crystal-based metasurfaces: response speed. The structure employs strong coupling through complementary patterns, enabling functionality with the ultra-thin liquid crystal layer. Furthermore, by adopting the active matrix driving method commonly used in flat-panel displays, the complexity of control wiring is reduced, allowing for 2D beamforming. The study’s outstanding performance, compared to other research globally, led to its recognition with the “Honorable Mention” award.

The IEEE AP-S/URSI, the largest international symposium in the field of antennas and propagation under the IEEE Antennas and Propagation Society, was held this year in Portland, USA. The 2023 Student Paper Competition received a total of 221 submissions, and Dae-Hyun Kim’s work stood out to earn an “Honorable Mention.”
