| 摘 要： | 在微分－Ｔｈｏｍｐｓｏｎ变换结合时域有限差分（ＦＤＴＤ）技术计算复杂目标的电磁散射特性的方法中，差分格式的构造和选取与解的精度存在着密度关系。本文将提出一种新的高精度差分格式，其数值实现进一步证实了Ｔｈｏｍｐｓｏｎ－ＦＤＴＤ方法能精确模拟任意形状目标的电磁散射过程

| Abstract: | When applying the method of Finite Difference Time domain (FDTD) technique combined with Thompson transformation to calculate electromagnetic scattering problems of complex objects,the construct or selection of difference schemes has an effect directly on the accuracy of numerical solution.In this paper,the new difference schemes that have high order accuracy are presented,the numerical results prove that Thompson-FDTD method can accurately simulate the electromagnetic scattering problems of arbitrary targets. |
