Abstract

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.

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.
