对较大的陨石和陆地单颗粒（尺寸范围为20 μm至120 μm）的光散射的研究表明，具有非常粗糙表面的不规则形状的深色不透明颗粒的散射特性类似于从黄道光测量中得出的经验散射函数的特征。透明或半透明的不规则形状粒子表现出完全不同的散射行为。此外，不规则的和多组分的蓬松颗粒的尺寸范围内的几个微米的微波模拟测量建模，以解释由彗星尘埃颗粒散射的光的正和负偏振。
The investigations of light scattering by larger meteoritic and terrestrial single grains (size range 20 μm to 120 μm ) demonstrate that the scattering properties of irregularly shaped dark opaque particles with very rough surfaces resemble the characteristic features of the empirical scattering function as derived from measurements of the zodiacal light. Purely transparent or translucent irregularly shaped particles show a quite different scattering behaviour. Furthermore irregular and multicomponent fluffy particles in the size range of a few microns were modelled by microwave analog measurements in order to explain positive and negative polarization of the light scattered by cometary dust grains.
