摘要: 本文导出了置于无限平行导体板间和置于屏蔽结构中的任意分层同轴介质谐振器的TE、TM模场分量表达式以及求解TE、TM模谐振频率的一般耦合特征方程。对于同轴(l=3层)介质谐振器进行了深入研究和大量计算,得到了同轴(l=3层)介质谐振器的主模和一些高次模的谐振频率随几何尺寸和介质特性变化的关系曲线和数据表。Abstract: The TE and TM mode field expressions and their general coupled characteristic equations of the dielectric coaxial resonators (any number of interfaces) placed between two parallel conducting plates or placed in shield are derived. Particularly, the dielectric coaxial resonator (three interfaces) is studied and calculated in detail. And curves and tables of dominant mode and some higher-order modes resonant frequencies varied with the resonantor geometry and dielectric properties are given.
