Abstract

In this paper, we present the analysis of electromagnetic scattering from arbitrarily shaped three-dimensional conducting objects coated with dielectric materials. The integral equation treated here is the combined field integral equation(CFIE). The objectives of this paper is to illustrate that only the CFIE formulation is a valid methodology in removing the interior resonance problem, which occurs at a frequency corresponding to an internal resonance of the structure. Numerical results of radar cross section for coated conducting structures are presented and compared with other available solutions.

본 논문에서는 유전체로 코팅된 3차원 임의 형상 도체의 전자파 산란 문제를 해석할 수 있는 결합적분방정식 (combined field integral equation, CFIE)의 해법을 제안한다. 본 논문의 목적은 구조물의 내부 공진주파수에서도 CFIE로부터 안정된 해를 얻을 수 있음을 보이는 것이다. 유전체로 코팅된 도체 구조에 대하여 제안된 방법으로 계산된 레이더 단면적(radar cross section, RCS)을 보이고 다른 방법에 의한 해들과 비교한다.
