CONGRESO Diffusion of Sound Waves by Sonic Crystals

Abstract

In this work we report de diffusion of acoustic waves by sonic crystals. We study different configurations of a sonic crystal formed by squared rods in a squared lattice with a finite rigid backing. Several resonances appear related with Fabry-Pérot resonances, the exostence of band gaps and the character of diffraction grating of the interface of the crystal
