Mishchenko, M., J. M. Dlugach, and D. W. Mackowski (2011), Light scattering by wavelength-sized particles “dusted” with subwavelength-sized grains, Optics Letters, 36, 337-339.

The numerically exact superposition T-matrix method is used to compute the scattering cross sections and the Stokes scattering matrix for polydisperse spherical particles covered with a large number of much smaller grains. We show that the optical effect of the presence of microscopic dust on the surfaces of wavelength-sized, weakly absorbing particles is much less significant than that of a major overall asphericity of the particle shape.
