用于电磁散射的矩量法择基问题的群方法

Applying the group theory to electromagnetic scattering problems for getting the base function has most.significance. This research includes two steps: firstly, by using group theory, we get the suitable base function to scattering object with complex symmetrical structure in MoM; secondly, for the.scattering object without complex symmetrical structure, we can divide it into two parts: one is the main part with some symmetrical structure, the other part which has no symmetrical structure can be.done by disturbance recurrence.

把群论用于电磁应用领域属于开创性事业。本研究内容包括两个部分：第一：利用群论的寻基方法，对于具有复合对称特征的散射体的散射情形找出矩量法求解的适定基函数。第二：对于虽整体上并无称性，可通过对称性破缺的方法，将散射体分为最大对称性部分和较小的微扰部分，再通过叠代的方式处理微扰部分，研究群方法的优化特征。
