Abstract

In this paper, we present the numerical analysis method for analyzing scattering characteristics of a rectangular waveguide with the conducting half cylinder using the mode matching method and compute scattering characteristics of a waveguide according to the rotation and changing radius of the half cylinder. Also, in conjunction with the generalized scattering method, the proposed method can be easily applied to a rectangular waveguide with cascade structure of conducting half cylinders. From the simulated result of a two pole filter, resonance frequency could be controlled by the rotation of half cylinders. The simulated result shows good agreement with the HFSS's result. The proposed structure and analysis method are easily applied to the design of waveguide components with conducting half cylinders.

본 논문에서는 모드매칭법을 이용하여 구형 도파관 내부에 금속의 Half cylinder에 의한 산란 특성을 해석하는 수치적 해석법을 제시하였고, Half cylinder의 반경 변화와 회전에 따른 산란 특성을 계산하였다. 또한, 제안된 방법이 일반산란계수법과 연계되었을 때 여러 개의 Half cylinder가 위치한 경우에도 적용 가능함을 보였다. 2 pole 필터의 계산 결과로부터 Half cylinder의 회전에 따라 공진 주파수의 조정이 가능함을 알 수 있었다. 계산 결과는 HFSS의 결과와 비교하여 잘 일치하였다. 본 논문에서 제시한 구조와 해석법은 튜닝 소자로 금속의 Half cylinder를 사용하는 도파관 관련 부품의 설계에 쉽게 이용될 수 있다.
