Coherent backscattering and Anderson localization of light


Aegerter, C M; Maret, G (2009). Coherent backscattering and Anderson localization of light. Progress in Optics, 52:1-62.

Abstract

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 coherent backscattering cone is based on experimental investigations of multiple scattering of light in various media over the last two decades. In addition, we discuss experiments on coherent backscattering using many other types of waves. In a second part, we discuss the experimental search for strong localization in the context of past and present experiments. This leads to a presentation of the most direct method to date to show effects of strong localization via time resolved transmission measurements. These recent experiments are discussed in detail and we draw some conclusions on the nature of the localization transition. The paper ends with an outlook on possible future experiments.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
