In strongly scattering media, however, this model is not quite correct because of interference effects like coherent backscattering. In this letter, coherent backscattering is taken into account by a modified, self-attracting random walk. Straightforward simulations of this model essentially reproduce the results of current theories on “non-classical” transport behavior, i.e. Anderson localization in 1D and 2D for any amount of disorder and a phase transition from weak to strong localization in 3D. However, in the strongly scattering regime corrections are necessary to account for the finite number of light modes due to their non-vanishing lateral extention. Within our model this correction leads to the observation that strong localization does not take place.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: The European Physical Journal B ; 26 (2002), 2. - pp. 235-240</dcterms:bibliographicCitation> <dc:language>eng</dc:language> <dcterms:isPartOf rdf:resource=""/> </rdf:Description> </rdf:RDF>
