研究了不同尺寸参数值下小层状板的后向散射特性与板厚、板宽比、层数、入射方向和入射光偏振态的关系。结果与半无限板的解析结果进行了比较。用离散偶极近似法计算了小片的相函数和相应的后向散射效率。发现反射峰的角宽度取决于尺寸参数和宽高比。利用半无限板的反射率来近似有限尺寸板的后向散射效率的准则与层数、入射角和偏振状态有关。
The backscattering properties of small layered plates are studied for various size parameter values with respect to the plate thickness, plate aspect ratio, number of layers, incident direction, and polarization states of the incident light. The results are compared with the analytical results for semi-infinite plates. The phase functions and the corresponding backscattering efficiencies of the small plates are computed with the Discrete Dipole Approximation method. The angular width of the reflection peak is found to depend on both the size parameter and the aspect ratio. The criteria for using the reflectance of semi-infinite plates to approximate the backscattering efficiencies of finite size plates are quantified with respect to the number of layers, incident angle, and polarization state.
