摘　　要：用严格模匹配与多模网络理论相结合的方法 ,对几种周期介质结构的传输特性进行了深入的分析 .包括两种有限长周期介质镜像波导滤波器 ;一种有限长变周期无辐射介质波导滤波器 ;一种无限长周期部分介质填充的矩形波导 .The transmission characteristics for different kind of periodic guiding structures were analyzed with a method of rigorous mode matching method combining with multimode network theory. The periodic structures include two types of periodic image waveguide filters: one is NRD guide dielectric filter with varying period, and the other is periodically and partially dielectric filled infinite rectangular guide. Experimental data indicate that the present method is accurate and effective.
