A finite element artificial transmitting boundary method is presented for electromagnetic wave scattering from a perfectly conducting circular cylinder and a number of concave objects.
采用有限元-人工透射边界法求出平面波在无限长圆柱上的散射近场，并与解析解进行比较，进而对几种凹面体电磁波散射近场求解。
The scattering energy is found to be dependent on the incident wave number and the radius of the circular hole.
并指出能量的散射与入射波波长和圆孔半径有关。
