Abstract

Transmission cross section characteristics as a measure of transmission efficiency has been analyzed numerically for the H-shaped and C-shaped small apertures in the infinite conducting plane when illuminated by a plane wave. It has been found that C-shaped aperture has the larger transmission cross section than that of H-shaped aperture under the condition of the same perforated aperture area. Main attention has been focused on studying the mutual coupling effect between two C-shaped apertures on the transmission cross section characteristic. Parallel configuration which is composed of two C-shaped apertures arranged along the x-axis and collinear configuration which is composed of two C-shaped arrayed along the y-axis have been investigated from the viewpoint of enhanced transmission cross section characteristics.

무한 도체 평면에 H-형태와 C-형태의 소형 개구가 놓여져 있는 경우에 평면파가 입사될 때 투과 효율의 척도인 투과 단면적의 특성을 분석하였다. 동일한 개구 면적에서 C-형태 개구가 H-형태 개구보다 더욱 큰 투과 단면적이 나타남을 알 수 있었다. 두 개의 C-형태 개구가 인접해 놓여 있을 때 투과 단면적의 특성 관점에서 상호 결합 효과를 연구하는데 보다 관심을 두었고, 투과 단면적이 더욱 증대된다는 관점을 두고 두 개의 C-형태 개구가 x축으로 놓여있는 평행 배열 구조와 C-형태 개구가 y축으로 놓여있는 동일선상 배열 구조를 조사하였다.
