Abstract

The higher mode cutoff frequencies in Crawford TEM cells computed by the Galerkin method(GM) describe in this paper. The authors also report the half mode boundaries to solve not only the cut-off frequencies of symmetric TEM cells and those of asymmetric TEM cells. It is shown that the measured resonant frequencies of the present symmetric TEM cells and a designed asymmetric TEM cell are agreed with the calculated results.

본 논문에서는 Crawford TEM cell들의 고조 모드 차단 주파수에 대한 해석 결과를 나타내었다. 1/2 모드 경계영역을 제시하고, 변수 분리에 기초한 Galerkin 법을 적용하여 해석하였다. 대칭형은 물론 비대칭형 TEM 셀에 대한 차단 주파수를 정확히 예측할 수 있었다. 기존 대칭형 TEM cell과 직접 제작된 비대칭형 TEM cell에 적용한 결과 측정치와 매우 일치하고 있음을 볼 수 있었다.
