摘要
利用散射体的几何和物理特征,减少用矩量法求解散射场过程中所需要的存储量和计算时间,是当前具有理论和实际意义的重要课题。本文利用群论方法,给出了处理对称与反对称结构电磁散射问题的统一方法和理论依据。
It is of both theoretical and practical importance to reduce the storage and CPU time of moment methods by utilizing the geometrical and physical features of the scatterer. An unified approach based on the group theory was presented to deal with the EM scattering from symmetric and anti-symmetric structures.
