Abstract

This paper reports the design of a novel acoustic beam aperture modifierusing gradient-index phononic crystals consisting of different solid cylindersembedded in a homogeneous epoxy background. Dispersion curves of the acousticwaves were calculated using a plane-wave expansion (PWE) method and theirpropagation in the proposed structure was simulated by a finite-elementtime-domain (FDTD) method. Computational experiments elucidate the effectivenessof the acoustic beam aperture modifier.
