아이리스 최적화 기법을 이용한 In-line형 6극 삼중모드 협대역 채널여파기의 설계
Design of in-line Six-pole triple-mode narrow-band channel filter using iris optimization method
초록
In this paper, we design tripel-mode channel filter using iris optimization technique and investigate its response. The cavity diameter is determined to resonate three orthogonal modes coincidently and inter-cavity iris is optimized in which one slot control one TE-TE mode and other TM-TM mode couplings simultaneously. Since the electric/magnectic field is variable due to slot position, the center position of the slot which handle coupling coefficients of two modes should be designe dwith optimizatin technique presented here. The implemented triple-mode filter in this paper saves its mass and volume upto 33% relating to the dual-mode filter, caused by the reduced number of cavities.
