摘要
利用模式匹配法分析了波导E面金属膜片的不连续结构,通过波导中不连续分界面切向场连续边界条件,推导了该不连续结构的散射矩阵,进而给出了相应的等效电路参数,分析了膜片厚度、放置位置对S参数以及等效电路参数的影响。
The discontinuous structure of Metal E-plane in waveguide is analyzed by Mode-Matching Method（MMM） in this paper. On the basis of the discontinuities of the waveguide by matching the tangible field, this paper yields the scattering matrix and then derives the equivalent circuit parameters. Finally, a three-resonator filter is analyzed in order to show the effect of the thickness and position on the S parameter and the equivalent circuit parameters.
