摘要
本文应用复源球面波理论,将高斯光束场按矢量球波函数展开,对高斯光束入射到单个球形粒子上时的弹性散射问题进行了理论分折。并对球形粒子在波束传播轴上时的远场散射光强角分布进行了数值计算,同时还与平面波散射的结果进行了比较。
The Gaussian beam expanding in terms of the vector spherical wavefunction realized by using complex-source-point spherical wave theory, theproblem of elastic scattering of Gaussian team by a spherical particle isanalysed theoretically. Numeral calculations for far field angular distributionof scattered irradiance are done for spherical farticle located on the beam axis.The distribution differences between scattering of a plane wave and beam waveare discussed.
