Chaotic scattering of microwaves

In this paper we analyze a recent experiment conducted in an anechoic chamb er, where the scattering of microwaves from an array of metallic cylinders was measured. This is a system which displays chaotic scattering in the sho rt wave limit. The analysis of the experimental data is aimed at elucidatin g the effects of the underlying chaos. We describe a robust numerical metho d which provides the scattering matrix for any number of nonoverlapping ref lecting cylinders. We use this method to calculate the scattering front one , two, and three cylinders and to compare the results in the numerical simu lations with those obtained in the experiment. Both simulations and measure ments validate the presented theory.
