Abstract

A new analytical method is presented for the shielding effectiveness(SE) of an enclosure with a dielectric-backed aperture. The previously proposed methods cannot consider the effect of the dielectric on the aperture. The comparisons among our method, previous method, and commercial programs give good correspondence. The method is used to calculate SE with varying permittivity and thickness of dielectric sheet, probe position, width and height of aperture.

본 논문은 유전체로 막힌 개구를 갖는 함체의 차폐 효과(SE)를 계산하는 해석적 방법을 제안한다. 제안된 방법은 기존의 방법으로 해석할 수 없는 유전체로 막힌 개구를 갖는 함체의 SE 해석이 가능하다. 제안된 방법의 타당성을 검증하기 위해 기존에 제시된 방법과 상용 프로그램의 SE 해석 결과를 비교 검증하였다. 제안된 방법을 이용하여 덮개 유전체의 유전율과 두께 변화, 함체 내 관측점 위치 변화, 개구의 폭과 높이 변화에 대한 SE 변화를 계산하였다.
