    • 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
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 collimated sound beams by three-dimensional sonic crystals 

      Cebrecos, A.; Romero García, V.; Pico, R.; Pérez Arjona, I; Espinosa Duró, Virginia; Sánchez Morcillo, V. J.; Staliunas, Kestutis (American Institute of Physics (AIP), 2012)
      Article
      Accés obert
      A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An efficient collimation of the beam behind the ...
