Within the generalized Lorenz-Mie theory framework, an analytic solution to Gaussian beam scattering by a rotationally uniaxial anisotropic sphere is presented. The scattered fields as well as the fields within the anisotropic sphere are expanded in terms of infinite series with spherical vector wave functions by using an appropriate expansion of the incident Gaussian beam. The unknown expansion coefficients are determined from a system of linear equations derived from the boundary conditions. Numerical results of the normalized differential scattering cross section are shown, and the scattering characteristics are discussed concisely.
在广义洛伦兹 - 米氏理论框架内，给出了旋转单轴各向异性球体对高斯光束散射的解析解。通过对入射高斯光束进行适当展开，将散射场以及各向异性球体内的场用球面矢量波函数的无穷级数展开。未知的展开系数由从边界条件导出的线性方程组确定。给出了归一化微分散射截面的数值结果，并简要讨论了散射特性。
