An explicit form of the Mueller matrix is given for an anisotropic sphere fulfilling the requirements of the Rayleigh-Gans-Debye (RGD) approximation. The angular dependences of single matrix elements are compared with Lorenz-Mie predictions for an isotropic sphere. Good agreement between the Lorenz-Mie model and that of RGD is observed where the latter is applicable. The magnitude and sign of the matrix elements depend on the size parameter kR (k = 2pi/lambda;R is the radius of the sphere) as well as on the magnitude and sign of the (ñ - 1)/Deltan parameter, where ñ is the relative refractive index and Deltan is the relative anisotropy of the sphere.
给出了满足瑞利 - 甘斯 - 德拜（RGD）近似要求的各向异性球体的穆勒矩阵的显式形式。将单个矩阵元素的角度依赖性与各向同性球体的洛伦兹 - 米氏预测进行了比较。在RGD模型适用的地方，观察到洛伦兹 - 米氏模型与RGD模型之间有良好的一致性。矩阵元素的大小和符号取决于尺寸参数kR（k = 2π/λ；R是球体半径）以及(ñ - 1)/Δn参数的大小和符号，其中ñ是相对折射率，Δn是球体的相对各向异性。
