我们介绍了高斯随机椭球（GE）的随机几何，并与离散偶极子近似，进行初步计算的光散射波长尺度GE粒子。在GE几何中，我们用三个半轴a >= B >= c来描述基椭球。轴比B：a和c：a表现为高斯随机球几何（GS）的形状参数之外的两个形状参数。我们比较的散射特性的GE颗粒的椭球。在椭球体上引入不规则性使角散射特性平滑，其方式类似于GS颗粒情况下球形颗粒特性的平滑。(C)2011爱思唯尔有限公司版权所有。
We introduce the stochastic geometry of a Gaussian random ellipsoid (GE) and, with the discrete-dipole approximation, carry out preliminary computations for light scattering by wavelength-scale GE particles. In the GE geometry, we describe the base ellipsoid by the three semiaxes a >= b >= c. The axial ratios b:a and c:a appear as two shape parameters additional to those of the Gaussian random sphere geometry (GS). We compare the scattering characteristics of GE particles to those of ellipsoids. Introducing irregularities on ellipsoids smoothens the angular scattering characteristics, in a way analogous to the smoothening of spherical particle characteristics in the case of GS particles.
