摘要
本文简述了各向异性介质FDTD方法 ,并用FDTD方法分析了三维各向异性有耗介质板的瞬态后向散射。根据各向异性介质板后向散射与入射电磁波极化方向有关的特点 ,利用其后向RCS的谐振特性估算介质板的横向介质参数。计算表明该方法可行且方便、快捷。
Using the FDTD method, the back scattering of a lossy anisotropic plate is analyzed when the plate is illuminated by a plane transient electromagnetic wave. Based on the resonance characteristics of the back scattering RCS, a reconstruction scheme for recovering the transverse permittivity of an anisotropic plate is proposed. The computed results show the availability and simplicity of presented method.
