Anderson localization occurs always in less than three dimensions in presence of white noise disorder. But when introducing correlations, as like is the case of the Random Dimer Model, a subset of eigenstates can be delocalized. It is a case of short-range correlation, here neighboring sites of identical site energy are assigned to appear as pairs, thus forming a dimer (1). This presentation is about the preparations towards an experimental study of the localization-delocalization transition in a one dimensional Random Dimer Model by emulating the tight-binding model in a microwave cavity with two types of dielectric scatterers. Recently the Anderson tight-binding model was successfully emulated with this experimental setup in order to investigate transport properties of Graphene like structures (2,3).
