Abstract

Based upon three level approximation and the steepest descent path(SDP) method, we consider an optimum choice of approximation path for derivation of new class of closed-flrm Green's functions which can lead to the analytic evaluation of MoM(Method of Moment) matrix elements. It is observed that the present method can give more accurate evaluation of the spatial Green's functions than the previous method, even without the advance investigation of the spectral functions, over a wide frequency range. In order to check the validity of the present method, some numerical results are presented.

본 논문에저는 MoM 행렬 요소의 해석적 계산이 가능한 새로운 형태의 closed-form 그린함수 유도를 위한 최적의 근사화 경로 선택을 3-단계 근사화 방법 및 SDP(Steepest Descent Path) 방법을 고려하여 제시하였다. 본 논문의 방법으로 유도된 새로운 형태의 closed-form그린함수 계산 결과가 기존의 방법과 달리 파수 영역 그린함수의 사전조사 없이도 넓은 주파수 범위에서 보다 정확한 결과를 주고 있음을 알 수 있었다. 본 논문이 제안하는 방법의 타당성을 확인하기 위하여 몇 가지 수치 결과들을 제시하였다.
