Localization of electromagnetic waves in random media

Abstract

The Helmholtz equation is the starting point to study an electromagnetic wave scattered by a random medium. For the special case of local scatterers a random matrix representation is derived. After a brief review of the concepts of weak localization (i.e. coherent backscattering) and strong (or Anderson) localization, an example for localization of electromagnetic waves in a one-dimensional array of scatterers is discussed using a numerical calculation. © 2003 Elsevier Science Ltd.
