Nonlinear self-collimated sound beams in sonic crystals
El Mokhtar Hamham, Noé Jiménez, Rubén Picó +3
We report the propagation of high-intensity sound beams in a sonic crystal, under self-collimation or reduced-divergence conditions. The medium is a fluid with elastic quadratic no…
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…
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…
Spatial Filtering of Sound Beams by Sonic Crystals
R. Pico, V. J. Sanchez-Morcillo, I. Perez-Arjona +1
We propose and numerically demonstrate an efficient cleaning of spatial structure (spatial filtering) of sound beams by propagating them through at least twodimensional sonic cryst…
