The theoretical solution for scattering by an arbitrary configuration of closely spaced parallel infinite cylinders buried in a lossy half space is presented in this paper. The refractive index and permeability of the half space and cylinders are complex in general. Each cylinder is radially stratified with a distinct complex refractive index and permeability. The incident radiation is an arbitrarily polarized plane wave propagating in the plane normal to the axes of the cylinders. Analytic solutions are derived for the electric and magnetic fields and the Poynting vector of backscattered radiation emerging from the half space. Numerical examples are presented to illustrate the application of the scattering solution to calculate backscattering from a lossy half space containing multiple homogeneous and radially stratified cylinders at various depths and different angles of incidence.
本文给出了埋于有耗半空间中紧密排列的平行无限长圆柱任意构型的散射理论解。半空间和圆柱的折射率及磁导率通常为复数。每个圆柱沿径向分层，具有不同的复折射率和磁导率。入射辐射是在垂直于圆柱轴线的平面内传播的任意偏振平面波。推导了从半空间出射的反向散射辐射的电场、磁场和坡印廷矢量的解析解。给出了数值算例，以说明散射解在计算包含多个均匀且沿径向分层的圆柱、处于不同深度和不同入射角的有耗半空间的反向散射中的应用。
