摘　　要：用模式匹配法分析矩形波导不连续性时,传统的方法是针对不同的不连续性推导出不同的表达式,分析方法不具有通用性,给程序实现带来了很大的不便.利用模式匹配法分析,推导出横向膜片、纵向插片中矩形阶梯广义散射矩阵的通用公式,使矩形波导不连续结构的处理方法简化统一,既适合单、多窗横向膜片,也适合单、多纵向膜片.设计了两种矩形带通滤波器实例,在相同配置和精度要求下,其结果与高频电磁场仿真软件吻合.In rectangular waveguide discontinuity analysis by mode matching, the traditional method infers a different expression according to a different discontinuity. The program creates a serious inconvenience, so there need be a unified approach to analyzing the rectangular step. This paper infers the unified generalized s-parameter matrix formula of the step in the thick diaphragm and in the E-plane septum by mode matching. Finally, two rectangular band pass filter examples are included. The curve results agree well and the calculation time is greatly shortened compared with the HFSS, which verifies the validity of this technique.
