Abstract

This paper presents the penetrated electric fields and resonant frequencies inside a metallic enclosure with aperture excited by an external dipole source. In the theoretical analysis, integral equations for the current distribution and electric field distributions on the aperture are solved by applying Galerkin\`s method of moments. The results show that the electric fields inside metallic enclosure is maximum at the near the aperture and resonant frequencies are the same as calculated of the enclosure without aperture. To verify the theoretical analysis the electric field inside enclosure and resonant frequencies are compared with the experimental results.

본 논문에서는 외부 다이폴 파원에 의해 합체의 개구를 통하여 침투하는 침투 전계와 함체의 공진 주파수 특성을 검토하고 있다. 이론해석 방법으로서는 외부 다이폴 파원의 전류분포 및 함체에 있는 개구의 개구면 전계분포에 관한 연립 적분방정식을 Galerkin의 모멘트 법으로 해석하고 있다. 이론해석의 결과, 침투전계는 개구면 부근에서 가장 크며, 함체의 공진 주파수는 개구가 없는 경우의 공진 주파수와 거의 일치하므로 함체의 크기가 결정되면 공진 주파수의 추정이 가능하다는 것을 알 수 있었다. 이론해석의 타당성을 화인하기 위하여 함체의 내부 전계 및 공진 주파수의 실험치와도 비교하고 있다.
