摘要

求解时谐电磁逆散射问题的算法得益于改进的正向求解能力，如电磁场和本构参数的高阶离散化。不连续伽辽金方法(DGM)提供了这样的高阶能力，可以通过局部变化的复介电常数和磁导率同时模拟电场和磁场。针对二维横向磁逆散射问题，提出了一种以DGM为正解的高斯-牛顿反演(GNI)算法。

Discontinuous Galerkin Gauss-Newton Inversion for electromagnetic imaging

Algorithms for solving time-harmonic electromagnetic inverse scattering problems can benefit from improved forward solver capabilities such as high-order discretizations of electromagnetic fields and constitutive parameters. The Discontinuous Galerkin Method (DGM) offers such high-order capabilities for simultaneously simulating both electric and magnetic fields from locally varying complex permittivity and permeability. In this work a Gauss-Newton Inversion (GNI) algorithm that adopts DGM as the forward solver is developed for 2D transverse magnetic inverse scattering problems.
