摘    要:基于Mie散射理论,对铌酸锂晶粒光散射特性进行了理论分析与数值计算,得到了散射强度分布、偏振度与散射角、散射强度与粒子尺寸参数,以及光学截面与粒子半径的关系。研究表明:前向散射占优势,并随粒子半径的增大而增强;当粒子半径为0.1 μm 左右,散射截面和吸收截面达到最大值。

关 键 词:Mie散射  光学截面  散射强度  铌酸锂

Abstract:Based on Mie scattering theory, the theoretical analysis and numerical calculation on LiNbO_3 microsphere particles light scattering characteristics were researched. The relationships between scattering intensity and scattering angle,polarization and scattering angle,scattering intensity and size parameter were obtained. The result showed that the forward scattering is dominated, and increases with increasing the radius of particle.The scattering cross section and absorbability cross section have the maximum value when particles radius is approximately 0.1 μm for LiNbO_3 nanoparticle.
Keywords:Mie scattering  optic section  scattering intensity  LiNbO_3
