Abstract

In this paper, we present a set of numerical schemes to solve the Muller integral equation for the analysis of electromagnetic scattering from arbitrarily shaped three-dimensional dielectric bodies by applying the method of moments(Mon. The piecewise homogeneous dielectric structure is approximated by planar triangular patches. A set of the RWG(Rao, Wilton, Glisson) functions is used for expansion of the equivalent electric and magnetic current densities and a combination of the RWG function and its orthogonal component is used for testing. Numerical results for a dielectric sphere are presented and compared with solutions obtained using other formulations.

본 논문에서는 임의 형상을 가지는 삼차원 유전체의 전자파 산란을 해석하기 위하여 모멘트법을 이용한 뮬러적분방정식의 새로운 해법을 제안한다. 매질이 균일한 유전체 표면을 평면 삼각형 패치로 모델링 하여, RWG (Rao, Wilton, Glisson)함수를 등가 전기 및 자기 전류밀도의 전개함수로 사용한다. 그리고 RWG 함수와 그 직교함수를 조합한 시험함수를 적용한다. 유전체구에 대하여 제안된 방법으로 계산된 수치 결과를 보이고 다른 공식에 의한 결과와도 비교한다.
