摘要

摘要针对具有阻抗边界条件的二维任意形状物体,提出了一种新的计算电磁学方法。本文提出的方法研究了二维物体在Leontovich边界条件下的e偏振电磁衍射。散射电场和磁场表示为相应的格林函数与障碍物表面感应电流的卷积积分。在应用边界条件得到积分方程后,按照计算电动力学中著名的辅助源法求解积分方程。首先比较了矩量法(MoM)、正交多项式法(OP)等不同方法的结果,其次比较了Dirichlet、Neumann和分数阶边界条件等不同边界条件的结果。对于不同形状的散射体,在不同的表面阻抗值下也得到了一些结果。

A fundamental approach: E-polarized electromagnetic wave diffraction by two dimensional arbitrary-shaped objects with impedance boundary condition
Abstract In the present study, a new methodology in computational electromagnetics is developed for two-dimensional arbitrarily-shaped objects with impedance boundary conditions. The proposed approach investigates the E-polarized electromagnetic diffraction by a two-dimensional object with the Leontovich boundary condition. The scattered electric and magnetic fields are expressed as the convolution integral of the corresponding Green’s function and the current induced on the obstacle surface. After obtaining integral equations by applying the boundary condition, the integral equations are solved as in the case of the method of auxiliary sources (MAS) which is a well-known method in computational electrodynamics. The results are compared with first, different methods such as the method of moments (MoM), orthogonal polynomials (OP), and second, different boundary conditions such as Dirichlet, Neumann, and fractional boundary conditions. Some results are also obtained for the different shape scatterers at some values of the surface impedance.
