本文提出了一种严格边界轮廓模式匹配（BCMM）方法，用于计算矩形波导中任意形状的H面和E面不连续性、结和/或障碍物的模式散射矩阵。对于具有一般轮廓的非均匀波导区域，场被展开成完整的柱面波函数集。全波展开允许直接严格地包括级联结构，例如组合的H和E平面弯曲。该方法的效率在迄今为止不能用模式匹配技术模拟的有用波导元件的严格设计中被证明：圆柱形后补偿H平面T形结、任意角度的斜接H平面和E平面弯曲、级联H平面/E平面弯曲、圆形后耦合滤波器、具有圆角的E平面滤波器、180度鼠笼结构和侧耦合双TE（311）/TE（113）模式滤波器。理论得到了测量的验证。
A rigorous boundary contour mode-matching (BCMM) method is presented for the efficient calculation of the modal scattering matrix of arbitrarily shaped H- and E-plane discontinuities, junctions, and/or obstacles in rectangular waveguides. For the inhomogeneous waveguide region with general contour, the field is expanded in the complete set of cylindrical wave functions, The full-wave expansion allows the immediate rigorous inclusion of cascaded structures such as combined H- and E-plane bends, The efficiency of the method is demonstrated at the rigorous design of useful waveguide components which could not be modeled by mode-matching techniques so far: cylindrical post-compensated H-plane T-junction, mitered H-plane and E-plane bends of arbitrary angle, cascaded H-/E-plane bends, circular post-coupled filter, E-plane filter with rounded corners, 180 degrees rat race structure, and side-coupled dual TE(311)/TE(113)-mode filter. The theory is verified by measurements.
