摘要

将有限元法应用于雷达吸波材料涂覆的二维圆柱体的开放边界模拟。从无限元计算得到的远场和散射体上的电流分布与解析解吻合较好。同时也说明了求解局部近场的优点。

FEM modelling of electromagnetic scattering from 2-D RAM-coated objects

The FEM (finite element method) technique using infinite elements to model the open boundary is applied to RAM (radar absorbing material)-coated 2-D circular cylinders. The far fields computed from both the infinite elements and the current distribution on the scatterer are shown to give good agreement with analytic solutions. The advantages of solving for the local near fields is also demonstrated.<>
