摘要
为进一步提高电大尺寸目标散射求解能力 ,采用了基于多层快速多极子方法的高阶方法。与低阶相比 ,该方法所需未知量数目大大减少 ,而计算精度不变 ,因而具有比传统多层快速多极子方法更高的计算效率。
To further speed up the ability of solution of electromagnetic scattering from the object with large electrical sizes, a higher order scheme of multilevel fast multipole algorithm (MLFMA) is introduced. Compared to the conventional MLFMA, the higher order scheme reduces greatly the unknown numbers required without losing of accuracy, and can attain much higher efficiency. The numerical results demonstrate the validity and efficiency of the scheme.
