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…
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…
