- The paper, titled 'Coil Array Technique With Maximum Tolerance to 2-D Misalignment for Wireless Power Transfer Systems,' showcases a multifunctional assistant coil array technology. This innovation ensures the sustained high efficiency of wireless power transfer systems, even under substantial misalignment between Tx and Rx coils. Unlike previous coil array techniques, the approach requires the integration of assistant coils solely on the Tx side, rendering it particularly well-suited for mobile applications. Nevertheless, it delivers superior performance, maintaining efficiency above 70% even under misalignments exceeding 100%, irrespective of the direction The research was conducted by Miss Seoyeon Yoon under the supervision of Prof. Yongshik Lee.

- Research from Prof. Yongshik Lee's Lab Published in IEEE Transactions on Antennas and Propagation
- The paper, titled “Dielectric Patterning Method for Enhanced RCS Reduction Effect Based on DBD Plasma”, demonstrates a technology that integrates a patterned dielectric layer with a DBD plasma generator, significantly increasing the effective electron density of the plasma and, consequently, dramatically enhancing the RCS (radar cross-section) reduction effect. The experimental results revealed that an RCS reduction effect of up to 34.7 dB was attained, surpassing the previous achievement by 10.7 dB. This marks the initial demonstration that plasma-based electromagnetic concealment technology is capable of providing the performance of well-established RCS reduction technologies, such as metasurfaces. This suggests a potential role for plasma-based technology in future electromagnetic concealment technologies. The primary contributors of the work are Mr. Jinwoo Jung (first author) and Prof. Yongshik Lee (corresponding author). This work was supported by ADD (Agency for Defense Development).
