摘　　要：从Maxwell方程出发 ,推导出平面波照射下手征介质涂覆导体目标表面等效电磁流的一般表达式 ,并基于切平面近似 ,给出了计算手征介质涂覆导体目标电磁散射的物理光学 (PO)解。在此基础上 ,计算了T形结构及锥柱结构的散射特性 ,分析了手征材料参数对电磁散射的影响 ,得到了一些有益的结果。Based on Maxwell's equations, an analytical formulation is derived for the equivalent currents on conducting objects coated with chiral material illuminated by a plane wave. By using the tangential plane approximation, the physical optics (PO) solutions are obtained. The backscattering of the T type structure and the cone cylinder geometry are computed with this method, the effect of different chiral parameters is discussed, and some useful conclusions are given. This work provides an efficient approach for fast prediction of the scattering by the electrical large conducting objects coated with chiral material.
