Extraordinary absorption of sound in porous lamella-crystals
J. Christensen, V. Romero-García, R. Picó +5
We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structu…
Wave focusing using symmetry matching in axisymmetric acoustic gradient index lenses
V. Romero-García, A. Cebrecos, R. Picó +3
The symmetry matching between the source and the lens results of fundamental interest for lensing applications. In this work we have modeled an axisymmetric gradient index (GRIN) l…
Formation of collimated sound beams by three-dimensional sonic crystals
A. Cebrecos, V. Romero-Garcia, R. Pico +4
A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An effic…
