以Mie理论为基础,用数值计算方法分析了金属球型颗粒的光散射特性,给出了金属颗粒对平行入射光的散射强度函数和散射偏振度的数值计算方法。利用Matlab软件模拟得到了散射光强度函数和偏振度随散射角和尺度参量变化的三维图。模拟结果表明:偏振峰个数随尺度参量的增大而增多,偏振峰之间的距离随尺度参量的增大而缩小。这种变化趋势可以作为检测金属颗粒粒径的理论依据。

The light scattering characteristics of spherical metal particles are analyzed by numerical calculation method based on the Mie theory. A numerical calculation method for intensity function and polarization of the parallel incident beam scattered by small spherical particles is presented. The 3D graph for the intensity function and polarization varying with the scattering angle and the scale parameter was obtained by Matlab software simulation. The results show that with the increasing of scale parameter the number of polarization peak increases and the distance between the polarization peaks decreases. The variation can be used as theoretical basis for the detection of metal particle size.
