    Acoustic behavior of the VEGA launch pad environment 
    Picó Vila, Rubén; Herrero-Durá, Iván; Sánchez Morcillo, Víctor José; Salmerón-Contreras, L. J.; García-Raffi, L. M. (Universidade do Porto, 2016-06-15)
    [EN] The acoustic pressure levels experienced by the spacecraft and launchers during the lift-off is due among other factor by the reflection of the sound waves on the launch pad. The acoustic load distribution in the area ...

    Broadband reduction of the specular reflections by using sonic crystals: A proof of concept for noise mitigation in aerospace applications 
    García-Raffi, L. M.; Salmerón-Contreras, L.J.; Herrero-Durá, Iván; Picó Vila, Rubén; Redondo, Javier; Sánchez Morcillo, Víctor José; Staliunas, Kestutis; Adkins, N.J.; Cebrecos, Alejandro; Jimenez, Noe; Romero García, Vicente (Elsevier, 2018-02)
    [EN] The broadband reduction of the specular reflections by sonic crystals (SCs) is theoretically and experimentally reported in this work. The analysed system consists of a sound source radiating a SC made of acoustically ...

    Gap Solitons in acoustic layered media 
    Salmerón Contreras, Luis José; García-Raffi, L. M.; Jimenez, Noe; Mehrem, Ahmed; Picó Vila, Rubén; Sánchez Morcillo, Víctor José; Staliunas, K. (Universidade do Porto, 2016-06-15)
    [EN] In this work we study numerically the existence of gap solitons in an acoustic media. To approach the problem a set of coupled-mode equations are given. In order to obtain a solitary wave in a real media, it is necessary ...

    Interacción de los ultrasonidos con medios viscosos 
    Salmerón Contreras, Luis José (Universitat Politècnica de València, 2014-02-17)
    Muchos sistemas en la naturaleza, cuando son excitados lejos del equilibrio, pueden auto-organizarse formando una gran variedad de patrones o estructuras como pueden ser el rayado de la piel de las cebras. Durante el siglo ...

    Nonlinear dispersive waves in repulsive lattices 
    Mehrem, Ahmed; Jimenez, Noe; Salmerón-Contreras, L. J.; García-Andrés, Francesc Xavier; García-Raffi, L. M.; Picó Vila, Rubén; Sánchez Morcillo, Víctor José (American Physical Society, 2017)
    [EN] The propagation of nonlinear waves in a lattice of repelling particles is studied theoretically and experimentally. A simple experimental setup is proposed, consisting of an array of coupled magnetic dipoles. By driving ...

    Propagación de ondas trasversales generadas con fuerza de radiación 
    Salmerón Contreras, Luis José (Universitat Politècnica de València, 2012-02-02)
    El estudio de la propagación de ondas transversales en el interior de un tejido aporta información acerca de la elasticidad de éste que puede emplearse para diseñar nuevas técnicas de diagnóstico médico. Sin embargo, la ...

    Reflection of sound by Sonic Crystals: an application to the aerospace engineering 
    García-Raffi, L. M.; Salmerón-Contreras, L. J.; Herrero-Durá, Iván; Picó Vila, Rubén; Redondo, Javier; Sánchez Morcillo, Víctor José; Cebrecos, Alejandro; Jimenez, Noe; Romero García, Vicente; Staliunas, K. (Universidade do Porto, 2016-06-15)
    [EN] From the acoustical point of view one of the most extreme events is the lift-off of a rocket. In such events, an enormous amount of energy is liberated in the form of acoustic waves that are reflected in the launch ...

    Reflexión de ondas acústicas en medios periódicos 
    Salmerón Contreras, Luis José (Universitat Politècnica de València, 2016-01-08)
    [EN] In the last decades, the control of the propagation of light, elastic and acoustic waves through periodic media has aroused great interest. These are known as photonic, phononic or sound crystals, respectively. These ...

    Second harmonic propagation in Coupled Oscillators 
    Mehrem, Ahmed; Sánchez Morcillo, Víctor José; Jimenez, Noe; Salmerón Contreras, Luis José; García-Andrés, Francesc Xavier; Picó Vila, Rubén; García-Raffi, L. M. (Universidade do Porto, 2016-06-15)
    [EN] In this work, we studied numerically, analytically and experimentally the nonlinear dynamics for a chain of magnates. Propagation the second harmonic depends on the medium parameters and the excitation signal (amplitude ...

    Solitary waves in nonlinear phononic crystals 
    Mehrem, A.; Picó Vila, Rubén; Sánchez Morcillo, Víctor José; García-Raffi, L. M.; Salmerón-Contreras, L. J.; Jimenez, Noe; Staliunas, K. (Universidade do Porto, 2016-06-15)
    [EN] We discuss two possible regimes of solitary wave formation in acoustic layered media. In the weakly dispersive limit, KdV-type solitons are formed, consisting of broad pulses with a width much larger than the lattice ...
