Acoustic Bessel-like beam formation by an axisymmetric grating
N. Jiménez, V. Romero-García, R. Picó +5
We report Bessel-like beam formation of acoustic waves by means of an axisymmetric grating of rigid tori. The results show that the generated beam pattern is similar to that of Bes…
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…
Enhancement of sound in chirped sonic crystals
V. Romero-García, R. Picó, A. Cebrecos +2
We propose and experimentally demonstrate a novel mechanism of sound wave concentration based on soft reflections in chirped sonic crystals. The reported controlled field enhanceme…
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…
