摘　　要：提出一种应用时域有限差分算法求解脉冲平面波斜入射时旋转对称体散射问题的方法.对斜入射脉冲平面波在圆柱坐标系下进行分解、应用总场/散射场连接边界、PML吸收边界条件.通过与矩量法分析结果的比较。We present a method for electromagnetic scattering with obliquely incident pulse plane wave using BOR-FDTD（body of revolution finite-difference time-domain） method. The obliquely incident pulse plane wave is expanded in a cylindrical coordinate and a total-field/scattered-field formulation is introduced as excitation. The method is validated by comparing with the method of moments. It shows good agreement.
