Experimental observation of the mobility edge in a waveguide with correlated disorder

The tight-binding model with correlated disorder introduced by Izrailev and Krokhin [Phys. Rev. Lett, 82, 4062 (1999)] has been extended to the Kronig -Penney model. The results of the calculations have been compared with micr owave transmission spectra through a single-mode waveguide with inserted co rrelated scatterers, All predicted bands and mobility edges have been found in the experiment, thus demonstrating that any wanted combination of trans parent and nontransparent frequency intervals can be realized experimentall y by introducing appropriate correlations between scatterers.
