      We predict and show the existence of unlocked evanescent waves in two dimensional periodic structures. In a one dimensional periodic structure an evanescent mode are located either at the center or at the boundary of the ...
    • 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
      Open Access
      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 ...
