提出了一种涉及傅里叶变换和组合场积分方程的数值公式，用于计算任意形状圆柱体中轴向槽或周向槽之间的互导纳。考虑两种情况：两个圆周槽之间的耦合和两个轴向槽之间的耦合。假设这些槽是由 TE/sub 10/波导模式激励的波导馈电孔径，模型中不包含高阶模式。将组合场积分方程 (CFIE) 公式与磁场积分方程 (MFIE) 结合使用来求解所得的二维积分方程。讨论了轴向槽情况的公式。针对轴向和圆周情况，给出了有关频谱离散化和截断的结果以及程序的准确性。通过与圆柱体的本征函数数据的比较证明了该过程的准确性。 >
A numerical formulation involving the Fourier transform and the combined-field integral equation is presented to calculate the mutual admittance between axial slots or circumferential slots in arbitrarily shaped cylinders. Two cases are considered: coupling between two circumferential slots and coupling between two axial slots. The slots are assumed to be waveguide-fed apertures excited with the TE/sub 10/ waveguide mode, with no higher-order modes included in the model. The combined field-integral equation (CFIE) formulation was used in conjunction with the magnetic field integral equation (MFIE) to solve the resulting two-dimensional integral equation. Formulations for the axial slot case are discussed. Results concerning the discretization and truncation of the spectrum, as well as the accuracy of the procedure, are presented for both axial and circumferential cases. The accuracy of the procedure is demonstrated by comparison with eigenfunction data for circular cylinders. >
