| 摘 要： | 本文应用严格场匹配法解决了介质加载圆柱腔的本征问题，计算了圆柱腔在纵向部分填充介质后ＴＥ０１ｎ模和ＴＭ０１ｎ模的本征频率和本征场型的变化。特别分析了本征模式在空气段为截止模的情况。本文的分析方法亦可应用到纵向部分填充介质的传输线和其它形状的谐振腔。

| Abstract: | In this paper, the eigen problems of cylindrical cavity filled wtih dielectric slabs are solved by means of rigorous field matching method. Changes of resonance frequencies and the distributions of TE01n mode, TE11n mode and TM01n mode in cylindrical cavity are evaluated. The evanescant modes in air section are considered especially. The method used in the paper could be applied to transmission line and other resonators filled with dielectric materials. |
