本文提出了计算由任意截面圆柱形波导馈电的任意形状天线辐射场的积分方程及其离散化方法。我们给结果标量场在二维Dirichlet和Neumann边界条件和（矢量）电场和磁场在三维空间。对于所有四种情况，方程的离散形式都以相同的格式表示。馈电模式可以是TM、TE或横向电磁（TEM）。文中还给出了一种数值计算任意形状圆柱形波导孔模的方法。
We present integral equations and their discretizations for calculating the fields radiated from arbitrarily shaped antennas fed by cylindrical waveguides of arbitrary cross sections. We give results for scalar fields in two dimensions with Dirichlet and Neumann boundary conditions and for (vector) electric and magnetic fields in three dimensions. The discretized forms of the equations are cast in identical format for all four cases. Feed modes can be TM, TE, or transverse electromagnetic (TEM). A method for numerically computing the modes of an arbitrarily shaped, cylindrical waveguide aperture is also given.
