一种分析电磁散射问题的快速算法

A Kind of Fast Algorithm for Analyzing Electromagnetic Scattering Problems

将基于特征谱的双步预处理方法与多分辨预处理方法结合,用来快速分析电磁散射问题。特征谱双步预处理方法有效地利用了多分辨预处理方法的等级特性,计算实例证实它有很高的计算效率。

This paper combines the two-step preprocessing method based on the characteristic spectrum with the multi-resolution preprocessing method to rapidly analyze the electromagnetic scattering problems. The spectral two-step preprocessing method effectively makes use of the grade char- acteristic of the multi-resolution preprocessing method. The calculated examples have proved that it has very high calculative efficiency.
