本文提出了一种用模式匹配法和傅里叶变换相结合的方法来描述矩形波导E/H面多端口结的特性。该方法是基于场理论全波方法。在该结中的主波导的电场和磁场表示为傅里叶积分，并在傅里叶变换域中匹配到由每个臂波导中的简正模扩展的孔径场。这产生了一组解析封闭形式的线性方程组来计算多端口系统的散射参数。对魔T结和非对称E/H面三端口结的数值算例验证了本文方法的准确性和实用性。
A rigorous and efficient method for characterizing E-/H-plane multiport junctions in rectangular waveguides is presented by using the mode-matching method combined with Fourier transform technique. The method is based on a field-theoretical full-wave approach. The electric and magnetic fields of a main waveguide in the junction are expressed in terms of Fourier integrals and matched in the Fourier transformed domain to the aperture fields expanded by the normal modes in each of arm waveguides. This yields a set of linear equations in analytically closed form to calculate the scattering parameters of the multiport systems. The numerical examples for a Magic-T junction and an asymmetric E-/H-plane three-port junction verify the accuracy and usefulness of the present method.
