| 摘 要： | 利用黎卡地贝塞尔函数模拟了不同粒子尺度的散射光强和偏振特性.当粒子尺度增加时,散射光强增加;水平偏振变得不对称,而垂直偏振没有变化;当粒子的折射率虚部增加时,散射光强减少.从粒子的这些散射特性和偏振特性,可以测量和分辨不同尺度的粒子.

| Abstract: | The scattering intensity and polarization properties of different size particles are simulated by the Ricatti-Bessel functions.As the size of particles increases,the scattering intensity increases;as the size of particles increases,the horizontal polarization becomes unsymmetrical while vertical polarization invariable;with the imaginary parts of complex refractive index increasing,the scattering intensity decreases.From these properties,various kinds of particles can be measured and taken apart. |
| |
| Keywords: | scattering intensity degree of polarization complex refractive index Mie's theory |
