| 摘 要： | 本文讨论了表面辐射条件(On-Surface Radiation Condition,简称OSRC)在求解二维均匀介质柱电磁场散射中的应用。其中利用求解均匀介质柱散射的三阶表面辐射条件算于讨论了入射场为横磁模(TM)和横电模(TE)的散射情况。文中计算了TM模入射时均匀介质柱的雷达散射截面(RCS),用OSRC求得的数值结果与严格解二者吻合得较好。

| Abstract: | In this paper,the application of OSRC to electromagnetic scattering from two-dimensional homogeneous dielectrtic cylinder is discussed.The third-order OSRC operator is used to analyse the scattering from a homogeneous dielectric cylinder illuminated by a TM or TE polarized plane wave.The results of radar cross-section of dielectric elliptical cylinder are provided,and they are in good agreee-ment with the exact solutions. |
