摘要
在应用ＦＤＴＤ求解电磁散射问题时， 需要引入吸收边界条件来截断计算空间。将Ｚ变换域上导出的几种新的吸收边界条件应用于三维电磁散射问题的分析。通过数值计算验证了这几种吸收条件的有效性并与ＭＯＭ 法等进行了比较。
In this paper, several new absorbing boundary conditions derived from Z transform domain are applied to three dimensional scattering problems. The validity of these absorbing boundary conditions are verified by numerical results, and compared with the super absorbing boundary condition etc.
