  text: We model negative polarization, which is observed for planetary regoliths
    at backscattering, solving a full wave problem of light scattering with a numerically
    exact Discontinuous Galerkin Time Domain (DGTD) method. Pieces of layers with
    the bulk packing density of particles close to 0.5 are used. The model particles
    are highly absorbing and have irregular shapes and sizes larger than the wavelength
    of light. This represents a realistic analog of low-albedo planetary regoliths.
    Our simulations confirm coherent backscattering mechanism of the origin of negative
    polarization. We show that angular profiles of polarization are stabilized if
    the number of particles in a layer piece becomes larger than ten. This allows
    application of our approach to the negative polarization modeling for planetary
    regoliths.
