초록

유전체 층으로 덮힌 임의형태 격자구조에서의 전자기 산란문제를 TE편파의 경우에 대하여 반사격자 관점과 누설파안테나 관점에서 해석하였으며, 주기그린함수와 모멘트방법을 이용하였다. 수치적 결과는 주기구조 파라미터에 따른 스펙트럴 모드별 상대산란파 전력과 복소전파상수등으로 나타내었다.

A numerical method for scattering of electromagnetic waves from a arbitrary shaped grating covered with dielectric slab is considered for TE polarization case from the viewpoints of both reflection grating problem and leaky wave antenna problem. The analysis is based on a periodic Green's function and the method of moments. Numerical results involving some combinations of geometric parameters are presented in terms of relative scattered powers of spectral modes and complex propagation constants.
