Abstract
The metal-insulator transition in a disordered system is described in terms of a divergence of the dielectric constant of the insulating phase (polarization catastrophe). The results of optical measurements are compared with theory within the framework of a scaling picture of the transition. Also described are recent theoretical and experimental developments regarding the role played by the low- frequency hopping modes that are characteristic of the disordered system, in the description of the transition.
