Abstract

ABSTRACT This paper presents a novel approach to accurately simulate the low frequency electromagnetic scattering of a homogeneous dielectric object in layered medium. The N-Muller surface integral equation (SIE) is utilized for accurate electromagnetic modeling at low frequency with a properly designed coefficient to cancel frequency singularity. Matrix-friendly layered medium Green’s functions are adopted and integrated into SIE to account for the effects of the inhomogeneous background. By using Galerkin method and rooftop basis functions, a well-conditioned impedance matrix is obtained and a rapidly converging iterative solution is achieved for low frequencies. Numerical results are provided to validate the proposed method and investigate its properties.

用Muller形成的SIE模拟层状介质中均匀物体的低频散射

本文提出了一种精确模拟层状介质中均匀介质物体低频电磁散射的新方法。利用N-Muller曲面积分方程(SIE)进行低频精确电磁建模，并设计适当的系数来抵消频率奇异性。采用矩阵友好的分层介质Green函数，并将其集成到SIE中，以考虑非均匀背景的影响。利用伽辽金方法和屋顶基函数，得到了条件良好的阻抗矩阵，并在低频情况下得到了快速收敛的迭代解。数值结果验证了该方法的有效性，并对其性质进行了研究。
