Microwave transmission spectra in regular and irregular one-dimensional scattering arrangements

There is a close correspondence between one-dimensional tight-binding syste ms, and the propagation of microwaves through a single-mode waveguide with inserted scatterers. Varying the lengths of the scatterers arbitrary sequen ces of site potentials can be realized. Exemplary results on the transmissi on through regular and random arrangements of scatterers as well as through sequences with correlated disorder are presented. (C) 2001 Elsevier Scienc e B.V.
