摘　　要：本文发展了一种能有效分析非均匀各向异性复杂目标的电磁散射特性的三维快速算法;该算法在切向 矢量有限元、即边棱元的基础上,采用近年来发展起来的快速多极子算法加速问题的求解,大大降低了计算复杂度,并 减小了计算内存.计算实例表明了该方法的有效性和可靠性.A fast hybrid algorithm is developed to analyze electromagnetic scattering by three-dimensional anisotropic inhomogeneous objects. Based on the vector finite element-edge element method (EEM), the fast multipole algorithm (FMA) is applied to the boundary condition and accelerates the EEM solution. It obviously reduces the computing complexity and memory requirement. The accuracy and efficiency of the method are verified by 3-D numerical examples.
