| 摘 要： | 采用快速多极子法（FMM）加速后的矩量法（MoM）求解由电磁场等效原理导出的关于均匀介质柱表面等铲电磁流的积分方程，进而计算其电磁散射特性，FMM的引入使计算时间和内存开销都从O(N^2）降到O（N^3/2），且并不增加多少复杂度。最后给出了一些介质柱体RCS的算例。

| Abstract: | The method of moments is accelerated by the fast multipole method (FMM) and applied to solve the integral equation with respect to the equivalent currents on the surface of a dielectric cylinder, and then the electromagnetic scattering analysis of the dielectric cylinder. After FMM acceleration, both the computing time and memory needs are reduced from O(N 2) to O(N 3/2 ) without increasing the complexity of implementation. |
