초록

메타 물질에서의 전자기파 유도 에너지 전달 제어에 관한 연구가 마이크로파 영역에서 실험 및 전산 모사를 통해 이루어졌다. 제시된 메타 물질은 기판을 사이로 두 개의 링 타입 공진기가 비대칭적으로 배열된 구조이고, 전자기파의 유도 에너지 전달이 편광 상태에 크게 의존함을 확인할 수 있었다. 본 연구는 마이크로파 제어 및 관련 응용 분야에 새로운 가능성을 제시할 수 있을 것이다.

The classical electromagnetically-induced transparency(EIT)-like switching in metamaterial was experimentally and theoretically demonstrated in the microwave-frequency region. The metamaterial unit cell consists of two identical split-ring resonators, which are arranged on both sides of a dielectric substrate with asymmetry. It is found that the classical EIT-like switching can be achieved by changing the polarization of the incident electromagnetic wave. The results of this study are promising for practical applications.
