本文提出了一种分析任意截面H面波导结的数值方法。这些结装载有任意形状的电介质或铁氧体。该方法是有限元法和边界元法的结合，并适用于区域和不与电介质或铁氧体，分别。为了证明该方法的有效性和实用性，在矩形波导中的一个有耗介质柱和铁氧体平板进行了详细的研究，计算结果与早期的理论和实验结果进行了比较。>
A numerical method is formulated for the analysis of H-plane waveguide junctions with arbitrary cross sections. The junctions are loaded with arbitrarily shaped dielectric or ferrite. The method is a combination of the finite-element method and the boundary-element method, and is applied to the regions with and without dielectric or ferrite, respectively. To show the validity and usefulness of the method, a lossy dielectric post and a ferrite slab in a rectangular waveguide are investigated in detail, and the computed results are compared with earlier theoretical and experimental results. >
