针对无界域上具有矩形结构多洞穴电磁散射问题的数值计算提出一种快速算法,该算法可快速计算尺寸较大及高波数的洞穴散射问题.数值算例验证了方法的有效性.
A fast algorithm was proposed for the numerical computation of the electromagnetic scattering by multiple rectangular cavities embedded on an infinite ground plane, the algorithm can be used to compute the scattering problems with large cavities and high wave numbers. The numerical experiments confirm the effectiveness of our method.
