摘要
介绍了利用矩量法求解线面复杂结构目标的电磁散射问题,并给出了一般的矩阵方程.并在以平面三角形电流为基展开的物理光学表面电流基础上,对矩量法和物理光学的混合方法的理论进行了细致和深入的研究,推导出了一般的矩阵方程表达式.仿真实例说明了该混合方法的精确性和高效性.
First, the problem of scattering by arbitrarily shaped objects is studied by the method of moment (MoM), when a thin wire antenna exists, with the general matrix equation given. Then a current based hybrid method combining the MoM with the physical optics (PO) approximation based on RWG for three-dimensional perfectly conducting bodies is studied profoundly, with the general matrix deduced. Finally, two examples about scattering from large electric objects are given to illustrate the hybrid methods accuracy and high efficiency.
