电磁学中的网络建模是处理正则结构和复杂结构散射问题的一种有效方法。由角区域（楔形）和平面层组成的几何结构现在可以用广义维纳-霍普夫技术来处理，该技术由谱域中的网络表示支持。即使网络表示在频谱平面本身是非常重要的，本文的目的是提出一个理论基础和一般程序的制定复杂的散射问题使用网络表示的广义Wiener Hopf技术基本上从波动方程开始。特别是，虽然光谱网络表示是相对众所周知的平面层，网络建模的角度区域需要一个新的理论，将在本文中开发。有了这个理论，我们完成了制定的网络方法，其有效性证明了一个复杂的散射问题的实际解决方案的GTD/UTD衍射系数和工程应用的总远场的应用。该方法可推广到其他物理领域。
Network modeling in electromagnetics is an effective technique in treating scattering problems by canonical and complex structures. Geometries constituted of angular regions (wedges) together with planar layers can now be approached with the Generalized Wiener-Hopf Technique supported by network representation in spectral domain. Even if the network representations in spectral planes are of great importance by themselves, the aim of this paper is to present a theoretical base and a general procedure for the formulation of complex scattering problems using network representation for the Generalized Wiener Hopf Technique starting basically from the wave equation. In particular while the spectral network representations are relatively well known for planar layers, the network modelling for an angular region requires a new theory that will be developed in this paper. With this theory we complete the formulation of a network methodology whose effectiveness is demonstrated by the application to a complex scattering problem with practical solutions given in terms of GTD/UTD diffraction coefficients and total far fields for engineering applications. The methodology can be applied to other physics fields.
