RIGOROUS MODE MATCHING ANALYSIS OF TRANSMISSION CHARACTERISTICS FOR PERIODIC DIELECTRIC STRUCTURES
周期介质结构传输特性的严格模匹配分析

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.
