Scattering Matrix of Finite length Coated Cylinder and Polarization Analyzing

摘要: 利用物理光学法及平面板块元法,对涂覆型圆柱的顶面和侧面的散射矩阵进行了推导和计算;利用一致性几何绕射理论分析了曲棱的一阶绕射场的散射矩阵;指出文献中的错误,然后通过散射矩阵分析目标散射场的极化特性参数和最优极化,给出了具体算例。

Abstract: With the method of physical optics and the uniform geometric theory of diffraction,the scattering matrix of the backscattered field of a finite length coated cylinder is presented.The polarization characteristic and the optimal polarization of the scattered field are analyzed.A example is also given in this paper.
