고 출력 전자기장(HPEM)의 영향은 시스템의 오작동, 고장 및 장비의 심각한 훼손을 야기시킬 수 있다. 따라서 업무 환경이 각종 전자 장비들로 대체 및 구성되어 가는 요즘, 인명과 재산을 보호하기 위해 고 출력 전자장에 대한 대책 연구가 필요하다. 이에 반해, 위상학적 해석 방법(topological analysis)은 해석 대상 구조에 대해 전자장의 이동 경로와 해석을 원하는 지점을 단순화시켜 해석하며, 대표적으로 Baum-Liu-Tesche(BLT) 방정식 기반의 해석법과 구역 설정(zoning)에 기반한 해석 방법 그리고 확률에 기초하고 있는 Power Balance Method (PWB)를 연동시킴으로써 효율적으로 해석할 수 있다. PWB 방법은 기존의 EM 시뮬레이션 방법의 비효율성을 극복하기 위한 하나의 대안으로 제시된 방법이다. 본 논문에서는 기존의 위상학적 해석 방법에 적용되는 기초 기술을 바탕으로 대형 구조에 적용될 수 있는 전자파 해석 방법을 제안한다. 그리고 최종적으로 PWB 방법과 full wave analysis 방법을 비교함으로써 PWB 방법의 장점과 이 방법의 도입 필요성에 대해 제안한다.
