多层快速多极子精度研究

A Study on Accuracy of the Multi-level Fast-Multipole Algorithm

精度分析是MLFMA研究中的重要内容。根据等效原理,提出一种针对任意形状目标散射MLFMA计算的精度验证方法,给出了精度验证方法的基本思路.使用这种方法,对层数和截断系数对MLFMA精度的影响进行了验证。

Accuracy analysis is an important part in the study of MLFMA. Based on Equivalence Principle, a method to validate the accuracy of multilevel fast multipole algorithm(MLFMA) for arbitrarily shaped targets is proposed. According to this method, the effect to accuracy of level and truncation coefficient is investigated.
