Limits of flexural wave absorption by open lossy resonators: reflection and transmission problems
J. Leng, F. Gautier, A. Pelat +3
The limits of flexural wave absorption by open lossy resonators are analytically and numerically reported in this work for both the reflection and transmission problems. An experim…
Broadband quasi perfect absorption using chirped multi-layer porous materials
Noé Jiménez, Vicent Romero-García, Alejandro Cebrecos +3
This work theoretically analyzes the sound absorption properties of a chirped multi-layer porous material including transmission, in particular showing the broadband unidirectional…
Asymmetric propagation using enhanced self-demodulation in a chirped phononic crystal
Alejandro Cebrecos, Noé Jiménez, Vicent Romero-García +3
Asymmetric propagation of acoustic waves is theoretically reported in a chirped phononic crystal made of the combination of two different nonlinear solids. The dispersion of the sy…
Nonlinear propagation and control of acoustic waves in phononic superlattices
Noé Jiménez, Ahmed Mehrem, Rubén Picó +2
The propagation of intense acoustic waves in a one-dimensional phononic crystal is studied. The medium consists in a structured fluid, formed by a periodic array of fluid layers wi…
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…
