本文提出了一种新的高阶积分算法，用于求解TE辐射下异质体的散射问题。这里，散射体由二维（2-D）有界区域内的（连续或不连续）变化的折射率n（x）表示。在给定入射场的情况下，通过对Lippmann-Schwinger积分方程进行高阶反演，得到了相应的Helmholtz方程的解。该算法运行在O（N log（N））操作，其中N是离散化点的数量。我们的方法提供了高精度的解决方案，在短的计算时间，即使是在散射体包含复杂的几何奇点的问题。
We present a new high-order integral algorithm for the solution of scattering problems by heterogeneous bodies under TE radiation. Here, a scatterer is represented by a (continuously or discontinuously) varying refractive index n(x) within a two-dimensional (2-D) bounded region. Solutions of the associated Helmholtz equation under given incident fields are then obtained by high-order inversion of the Lippmann-Schwinger integral equation. The algorithm runs in O(N log(N)) operations, where N is the number of discretization points. Our method provides highly accurate solutions in short computing times, even for problems in which the scattering bodies contain complex geometric singularities.
