Abstract

In this paper, simulation results of an electromagnetic field and mode distributions in a cylindrical reverberation chamber were presented. Reverberation chamber is an alternative test facility for a semi anechoic chamber, which is widely used for the analysis and measurement of electromagnetic interference and immunity tests. The method of computing the number of modes in a cylindrical reverberation chamber was presented and the number of modes in a cylindrical reverberation chamber with the same volume was compared with the different ratio of radius to height. The FDTD method was used to produce field characteristics inside of rectangular, right-angled isosceles triangular, and cylinder type reverberation chambers with the same test volume.

본 논문에서는 전자파 장해 및 복사내성 측정에 사용되는 준전자파 무반사실의 대용 방법으로 활용될 수 있는 전자파 잔향실 중에서 원통형 구조 전자파 잔향실의 전자기장 특성과 모드 분포를 연구하여 원통형 구조 전자파 잔향실의 모드 수 계산법을 제시하였으며, 이것을 사용하여 체적이 동일한 원통형 전자파 잔향실의 모드수를 반지름과 높이 비에 따라 비교 분석하였다. 또한 각각의 체적이 동일한 직사각형, 직각 이등변 삼각형, 원통형의 전자파 잔향실의 필드 균일도를 FDTD(Finite-Difference Time-Domain)를 이용하여 비교 해석하였다.
