Abstract

The localization of the electron wave functions is a well-known concept in contemporary condensed matter physics. It originates from investigations of the electron transport in disordered solids, usually semiconductors [1]. In such media the propagation of electrons is altered by the presence of a random potential. As this phenomenon is completely based on the interference effects in multiple elastic scattering and since interference is a common property of all wave phenomena, many generalizations of the Anderson localization to other matter-waves (neutrons) as well as classical waves (electromagnetic and acoustic waves) have been proposed [2, 3, 4, 5, 6]. In this paper we focus our attention on electromagnetic waves. There is a variety of experimental investigations in this case, both in the optical and microwave domains. Weak localization, manifesting itself as enhanced coherent backscattering, is now experimentally established beyond any doubts [7, 8, 9, 10]. Weak localization is relatively well understood theoretically [11,12,13] and, as the coherent backscattering affects the diffusion constant describing the propagation of electromagnetic waves in strongly scattering random media, it is the precursor of strong localization.
