A two-dimensional FD-TD method is used for the analysis of H-plane discontinuities of rectangular waveguide loaded with dielectric post. The dieclectric post resonances and the application of measurement of permittivity constant are discussed.

• 本文采用二维FD-TD分析加载有耗介质柱的矩形波导H面不连续性；对多层有耗介质柱体在波导中的不连续性引起的谐振以及在介电常数测量方面的应用进行了深入的讨论；数值计算与已有文献结果相符.
