Coherent Backscattering and Anderson Localization of Light
In this review we discuss localization of waves by multiple scattering. In the weak case, also known as coherent backscattering, there is a twofold enhancement of the reflected intensity in the back direction. We discuss the origin of this effect, its shape with reflection angle as well as the influence of finite sample size and absorption on this shape. This discussion of the properties of the...

متن کاملDiffuse Beam : Coherent Backscattering and Localization
On the basis of reciprocity, interference between two opposite paths ean be argued to be constructive in the backscattering direction of, for instance, a slab geometry, and exactly as large as the conventional diffuse background calculated from (1.8). At backscattering, the equation of radiative transfer is thus 100 % wrong! As always, the width of an interference effect is roughly given by the...
متن کاملCoherent Backscattering of Light by Cold Atoms
Light propagating in an optically thick sample experiences multiple scattering. It is now known that interferences alter this propagation, leading to an enhanced backscattering, a manifestation of weak localization of light in such diffuse samples. This phenomenon has been extensively studied with classical scatterers. In this letter we report the first experimental evidence for coherent backsc...
