Abstract

Application of Kobayashi potentials (KP) is extended to the electromagnetic (EM) diffraction from the parallel-plate multiport. Standard integral identities are used for problem formulation, without the direct use of Weber-Schafheitlin (WS) integrals. The Fourier function space is exploited for the construction of the governing linear system of equations. A simple strategy is suggested for the evaluation of the required improper integrals. Two-dimensional T- and X-junctions are studied as special cases. Numerical results are validated through convergence test and asymptotic analysis. It is shown that whenever the wave number in the whole problem domain is positive, no real power transfers to the diffracted field in the horizontal section of the aforementioned structures.

小林势法平行板多孔衍射

将小林势(KP)的应用扩展到平行板多孔口的电磁衍射。标准积分恒等式用于问题表述，而不直接使用韦伯-沙夫海特林(WS)积分。利用傅里叶函数空间来构造控制线性方程组。提出了一种简单的策略来计算所需的反常积分。二维T结点和x结点作为特例进行了研究。通过收敛性检验和渐近分析验证了数值结果。结果表明，当整个问题域中的波数为正时，在上述结构的水平截面上没有实际的功率传递给衍射场。
