초록

플랜지된 평행 평판 도파관의 슬릿을 통한 전자기적인 결합문제를 고려하였다. 결합 슬릿 근처 도파관 내 $.$외부의 무효전력을 반영한 슬릿의 등가 어드미턴스를 구하고, 슬릿의 폭이 매우 좁은 경우에서의 최대결합 메커니즘을 규명하였다. 도파관의 높이, 슬릿의 폭 및 슬릿의 변위 등과 같은 구조적인 파라미터들이 복사 특성에 미치는 영향을 관찰하였다.

The problem of electromagnetic coupling through a slit in a flanged parallel-plate waveguide is considered. The equivalent slit admittance associated with reactive powers near the coupling slit inside and outside the waveguide has been obtained. The maximum coupling mechanism for the case of narrow slit has been quantitatively discussed. The effects of various geometrical parameters such as guide height, slit width, and slit of offset on the radiation characteristics of the geometry have been investigated.
