本文是對於金屬箔片插入式微波導波管進行研究。我们分析此結構和傳統帶通濾波器不同﹐使用波模匹配法分析濾波器的不連續面特性以及討論在不連續面波導問題之解決及探討一般總合波模之方法。這種結構具有半波長諧振腔加上插入金屬箔片完全對稱呈現出之特性。發展最佳化的設計程序和演繹法的使用對完成正確的濾波器設計是必要的。

The thesis mainly focuses on the study of waveguide microwaves filters with metal septum inserts. We analyze the geometry of the metal septum inserts with the different in the conventional pass band waveguide filters. To analyze of filters discontinuities by the mode matching method and discuss the case for a complete change of emphasis in the solution of waveguide discontinuity problems and to present a general method of normal mode summation. The design of this structures are waveguide metal insert bandpass filters with half-wave resonators coupled with one another by means of longitudinally oriented. An optimization of the design procedure and the algorithm using is developed. The optimization often is required in practice for the accurate design of these filters.
