Accurate Measurement of Backscattered Light from Random Media

Anderson localization is known as the phenomena of a dramatic change in the transport properties of electrons when they are subject to a spatially random potential. [1] Electron waves are multiple scattered and as a consequence of interference, the diffusion constants vanishes. The dimension of the system plays a crucial role for the occurrence of Anderson localization. In one and two dimensions any de-gree of disorder will lead to a finite localization length, whereas in three dimensions first a critical mean-free path should be reached to enter the localized regime: (1)
