Abstract

Comparative study on the total transmission(zero reflection) has been done between two FSS structures which are coqmposed of the resonant aperture and the nonresonant aperture. It has been found that, the FSS of the resonant aperture has much larger ratio ${\lambda}$/T of wavelength ${\lambda}$ to array periodicity T than that of the FSS of the nonresonant aperture for the total transmission(or zero reflection). Also the operating frequency can be made to be significantly reduced by using such a resonant structure. This physical situation is thought to be similar to that of EOT(Extraordinary Optical Transmission) phenomenon, in optics area.

공진되는 개구와 비공진 개구로 구성되는 두 가지 형태의 FSS 구조에 대해 전부 투과되는 응답을 비교 연구하였다. 입사파가 전부 투과할 때 공진 개구의 FSS 구조는 파장 ${\lambda}$ 대 배열 주기 T의 비에 대해 비공진 개구의 FSS인 경우보다 더 큰 비를 가짐을 알 수 있었고, 또한 동작 주파수는 공진 구조를 이용함에 의해 상당히 낮출 수 있다. 이러한 물리적 상황은 현재 물리학 분야에서 널리 연구되고 있는 공진형의 특이한 광투과 현상과 유사한 성질을 지닌다고 사료된다.
