摘要

我们考虑了三维凸散射体对高频散射场的精度提高。仔细研究了凸散射体产生的Fock电流。在此基础上,提出了具有频率无关负载和误差可控精度的Fock电流数值计算方法。然后,采用Fock电流和增量长度衍射系数(ILDC)技术,清晰地表达了散射场。与物理光学(PO)散射场相比,采用Fock电流方法可以显著提高散射场的精度。

An efficient numerical contour deformation method for calculating electromagnetic scattered fields from 3-D convex scatterers
We consider the accuracy improvement of the high frequency scattered fields from 3-D convex scatterers. The Fock currents from the convex scatterers are carefully studied. Furthermore, we propose the numerical contour deformation method to calculate the Fock currents with frequency independent workload and error controllable accuracy. Then, by adopting the Fock currents and the incremental length diffraction coefficient (ILDC) technique, the scattered fields are clearly formulated. Compared to physical optics (PO) scattered fields from 3-D convex sphere, numerical results demonstrate significant accuracy enhancement of the scattered field via the Fock current approach.
