| 摘 要： | 本文采用 OSRC—GMT 研究了共焦均匀介质覆层导电椭圆柱的电磁散射特性。文中仅讨论了横磁(TM)波散射的情况、而横电(TE)波的情况可按同样方法分析。本中给出了用OSRC—GMT 方法求得的日标散射方向图的数值结果。数值计算表明,该方法求得的解与精确解有着良好的吻合。

| Abstract: | In this paper,the electromagnetic scattering properties of a homogeneous dielectric-coated confocal conducting elliptic cylinder using OSRC-GMT are investigeted.Only the transverse magnetic(TM) case is considered here,while the transverse electric(TE) case can be treated in the same way.Numerical results by means of OSRC-GMT are presented for echo width pattern.It is shown that this solution can give the results which are in good agreement with that of the exact solution. |
