摘　　要：本文以有限元方法(FEM)为基础,结合边界积分方程(BIM)这一开域边界条件的混合有限元算法实现对目标散射特性问题的分析。本文以一个介质涂敷金属圆柱为例应用有限元/边界积分方程法(FEM-BIM)实现计算结果,并与精确结果进行对比,吻合很好。Using the hybrid Finite Element Method （FEM）, combined with Boundary Integral Method （BIM）, this paper analyzes the electromagnetic scattering properties of objects. Here an example of a cylindrical metal has been presented, the results have been computed by the hybrid FEM and show the accuracy and validity compared to those published in literature, good agreements are obtained.
