Abstract

EMI problem is very important in a printed circuit board design. This paper deals with image plane as one of the most effective method to reduce EMI in PCB. The shielding performance of one and two layers of image planes of finite width and length is analyzed by the method of moments based on the triangular surface patch model. The current distributions were modeled as two simple line sources. It is demonstrated that proper triangulation should be made so as to take two basis functions in the boundary triangles of the surface.

영상평면을 사용하면 인쇄회로기판(PCB)의 전자파 복사를 효과적으로 감소시킬 수 있다. 이 논문은 이층 유한 영상평면이 PCB 로부터 방출하는 불요 전자파에 미치는 영향을 분석한 것이다. 유한 영상평면 구조의 해석을 삼각형 patch 모델을 모멘트 기법에 적용하여 이루어졌다. 기존에 보편적으로 사용하던 삼각형 분할방법을 개선하여 표면의 경계에 있는 삼각형에서 두 개의 기저함수를 삼각형 분할방법을 제안하고 그 결과가 수치해석의 정확도에 미치는 영향을 비교분석하였다.
