Abstract
A lattice model of a -dimensional disordered system is considered. The model is studied by a Migdal-Kadanoff renormalization-group transformation. In particular, localization in a macroscopically inhomogeneous medium is considered, and it is demonstrated that macroscopic disorder (above the percolation threshold) does not affect the critical exponents of the Anderson transition.
