Perfect absorption in mirror-symmetric acoustic metascreens
V. Romero-García, N. Jiménez, J. -P. Groby +5
Mirror-symmetric acoustic metascreens producing perfect absorption independently of the incidence side are theoretically and experimentally reported in this work. The mirror-symmet…
Aerogel-based metasurfaces for perfect acoustic energy absorption
Antonio A. Fernández-Marín, Noé Jiménez, Jean-Philippe Groby +2
The unusual viscoelastic properties of silica aerogel plates are efficiently used to design subwavelength perfect sound absorbers. We theoretically, numerically and experimentally…
Holograms to focus arbitrary ultrasonic fields through the skull
Sergio Jiménez-Gambín, Noé Jiménez, José María Benlloch +1
We report 3D-printed acoustic holographic lenses for the formation of ultrasonic fields of complex spatial distribution inside the skull. Using holographic lenses, we experimentall…
Rainbow-trapping absorbers: Broadband, perfect and asymmetric sound absorption by subwavelength panels with ventilation
Noé Jiménez, Vicent Romero-García, Vincent Pagneux +1
Perfect, broadband and asymmetric sound absorption is theoretically, numerically and experimentally reported by using subwavelength thickness panels in a transmission problem. The…
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…
Quasi-perfect absorption by sub-wavelength acoustic panels in transmission using accumulation of resonances due to slow sound
Noé Jiménez, Vicent Romero-García, Vincent Pagneux +1
We theoretically and experimentally report sub-wavelength resonant panels for low-frequency quasi-perfect sound absorption including transmission by using the accumulation of cavit…
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…
Ultra-thin metamaterial for perfect and omnidirectional sound absorption
Noé Jiménez, Weichun Huang, Vicent Romero-García +2
Using the concepts of slow sound and of critical coupling, an ultra-thin acoustic metamaterial panel for perfect and omnidirectional absorption is theoretically and experimentally…
What determines large scale galaxy clustering: halo mass or local density?
Arnau Pujol, Kai Hoffmann, Noelia Jiménez +1
Using dark matter simulations we show how halo bias is determined by local density and not by halo mass. This is not totally surprising, as according to the peak-background split m…
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…
Time-domain simulation of ultrasound propagation in a tissue-like medium based on the resolution of the nonlinear acoustic constitutive relations
Noé Jiménez, Francisco Camarena, Javier Redondo +3
A time-domain numerical code based on the constitutive relations of nonlinear acoustics for simulating ultrasound propagation is presented. To model frequency power law attenuation…
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…
A supersonic crowdion in mica: Ultradiscrete kinks with energy between K recoil and transmission sputtering
J. F. R. Archilla, Yuriy A. Kosevich, Noé Jiménez +2
In this chapter we analyze in detail the behaviour and properties of the kinks found in an one dimensional model for the close packed rows of potassium ions in mica muscovite. The…
Nonlinear Acoustics FDTD method including Frequency Power Law Attenuation for Soft Tissue Modeling
Noé Jiménez, Javier Redondo, Víctor Sánchez-Morcillo +3
This paper describes a model for nonlinear acoustic wave propagation through absorbing and weakly dispersive media, and its numerical solution by means of finite differences in tim…
