We apply the discrete dipole approximation method and a model of random irregular particles. Our results confirm water ice composition of the cm-sized chunks detected by the NASA Deep Impact space probe in the vicinity of the nucleus of Comet 103P/Hartley 2. The index of the power-law size distribution in this case can be constrained to the range n ≈ 3.3–4.3. For the other considered comets the circular polarization ratio can be reproduced with variations of the power index between 2 and 5."}],"publication_identifier":{"issn":["0004-6361","1432-0746"]},"publisher":"EDP Sciences","file_date_updated":"2018-09-03T14:05:33Z","article_type":"original","keyword":["tet_topic_scattering"],"intvolume":"       608","ddc":["530"],"status":"public","page":"A20","date_created":"2018-07-10T10:19:01Z","author":[{"first_name":"Shraddha","last_name":"Dogra","full_name":"Dogra, Shraddha"},{"id":"26059","full_name":"Grynko, Yevgen","last_name":"Grynko","first_name":"Yevgen"},{"full_name":"Zubko, Evgenij","last_name":"Zubko","first_name":"Evgenij"},{"last_name":"Förstner","first_name":"Jens","id":"158","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"}],"title":"Radar backscattering from a large-grain cometary coma: numerical simulation","volume":608,"has_accepted_license":"1","doi":"10.1051/0004-6361/201730801","publication":"Astronomy & Astrophysics","year":"2017","language":[{"iso":"eng"}],"user_id":"158","citation":{"short":"S.
