摘要
利用模式匹配的基本思想,结合复功率守恒法,考虑膜片厚度,推导出了矩形波导感性膜片不连续性的广义散射参数矩阵公式.利用所得公式,分析了膜片厚度和长度对膜片传输特性的影响,设计了一个7腔单边感性膜片带通滤波器,在相同配置和精度的要求下,结果与高频电磁场仿真软件比较,吻合良好,计算时间比高频电磁场仿真缩短了近99%.
The generalized S-parameter matrices of rectangular inductive irises are calculated based on a rigorous mixed method of the Mode Matching Method and the Conservation of the Complex Power Technique （CCPT）. The influence of the thickness and length nf the irises upon the transmission characteristic is analyzed, which includes the influence of higher order modes. Finally a seven-cavity band-pass filter of unilateral inductive irises is designed. The curve results agree well and the calculation time is greatly shortened compared with the HFSS, which verifies the validity of this technique.
