  • Acoustically penetrable sonic crystals based on fluid-like scatterers 

    Cebrecos, A.; Romero García, Vicenç; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Botey Cumella, Muriel; Herrero Simon, Ramon; Cheng, Yu Chieh; Staliunas, Kestutis (2015-01-21)
    Article
    Open Access
    We propose a periodic structure that behaves as a fluid-fluid composite for sound waves, where the building blocks are clusters of rigid scatterers. Such building-blocks are penetrable for acoustic waves, and their properties ...
  • Enhanced transmission band in periodic media with loss modulation 

    Cebrecos, A.; Pico Vila, Rubén; Romero García, Vicenç; Yasser, A.M.; Maigyte, Lina; Herrero Simon, Ramon; Botey Cumella, Muriel; Sánchez Morcillo, Victor José; Staliunas, Kestutis (2014-11-17)
    Article
    Open Access
    We study the propagation of waves in a periodic array of absorbing layers. We report an anomalous increase of wave transmission through the structure related to a decrease of the absorption around the Bragg frequencies. ...
  • Enhancement of sound by soft reflections in exponentially chirped crystals 

    Cebrecos, A.; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Staliunas, Kestutis; Romero García, Vicenç; Garcia Raffi, Luis Miguel (2014-12-01)
    Article
    Open Access
    The enhancement of sound inside a two dimensional exponentially chirped crystal during the soft reflections of waves is experimentally and theoretically explored in this work. The control of this enhancement is achieved ...
  • Formation of high-order acoustic Bessel beams by spiral diffraction gratings 

    Jimenez, Noe; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Romero García, Vicenç; Garcia Raffi, Luis Miguel; Staliunas, Kestutis (2016-11-23)
    Article
    Open Access
    The formation of high-order Bessel beams by a passive acoustic device consisting of an Archimedes' spiral diffraction grating is theoretically, numerically, and experimentally reported in this paper. These beams are ...
  • Nonlinear self-collimated sound beams in sonic crystals
