AbstractThe light scattering properties of a rough surface with feature size comparable to the wavelength of interest, which is similar to the surface consisting of coarse regolith, are estimated from Mie theory for representing the roughness as an ensemble of noninteracting spheres. It is found that a disk-integrated linear polarization deduced from singly scattered rays by Mie theory is smaller than that resulting from Fresnel reflection for a rough surface of fine regolith. In addition, negative polarization in the back scattering region observed in asteriods is well described by a mixing model of coarse and fine regoliths.
