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.","lang":"eng"}],"doi":"10.1016/j.icarus.2022.115099","page":"115099","file":[{"file_name":"2022-06 Grynko - Icarus - Negative polarization of light at backscattering from a numerical analog of planetary regoliths.pdf","file_id":"31575","file_size":1419286,"creator":"fossie","date_updated":"2022-06-01T18:56:44Z","date_created":"2022-06-01T18:56:44Z","relation":"main_file","content_type":"application/pdf","access_level":"open_access"}],"ddc":["530"],"publication_status":"published"}
