Abstract

A compact representation of Green function is proposed by applying the discrete wavelet concept in the k-domain, which can be used for the acceleration of scattered field calculations in integral equation methods. Since the representation of Green function is very compact in the joint spatio-spectral domain, it can be effectively utilized in the fast computation of radiation integral of electromagnetic problems. A mathematical expression of Green function based on the discrete wavelet concept is derived and its characteristics are discussed.

파수 영역(k-domain)에서 웨이블릿 변환 개념을 적용한 그린 함수 표현법은 적분 방정식에 활용할 때 전자파 해석의 고속화 계산에 사용할 수 있다. 그 표현 식은 기존의 표현에 비해서 매우 간결하기 때문에 전자파 해석의 방사 적분 계산 시간을 줄이는데 효과적으로 사용될 수 있다. 그린 함수의 이산 웨이블릿 개념을 이용한 수학적인 표현 식을 유도하고 그 특성에 대하여 설명하고자 한다.
