| 摘 要： | 提出了应用有限元法结合吸收边界条件分析二维导体柱的电磁散射特性.首先利用一阶吸收边界条件来截断散射体外的无限区域,然后应用有限元法进行分析,形成矩阵方程,最后应用多波前法求解该方程.作为算例,分别计算了无限长理想导体方柱和圆柱对平面电磁波的雷达散射截面,结果与有关文献一致,数值结果表明了该方法的有效性.

| Abstract: | In this paper, the finite-element method with absorbing boundary condition (ABC) is proposed for two-dimensional metal cylinder scattering. First, the absorbing boundary conditions(ABC) of first order is applied at the terminating infinite domain out metal cylinder. Then the finite-element method is used to analysis of the scattering property of metal cylinder and the matrix equation is obtained. Last, the multifrontal method is applied to solve the equation. As the verification example, the radar cross section(RCS) by infinite square post and circle cylinder of perfect electric conductor are obtained. The results in this paper agree well with those in previous works. Numerical results demonstrate its accuracy and efficiency. |
