| 摘 要： | 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。实际应用表明该方法具有图象清楚，过程简单，适应性强等优点，可有效解决分层介质，非均匀介质中各种复杂的散射问题，亦可广泛应用于声波等其他类波的散射问题。

| Abstract: | 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.In practice,the method is more simple,flexible and can give clearer physical pictures.It can be applied to solve complicated scattering problems in layered and inhomogenious media and to solve various acoustic or mechanical wave scattering problems. |
