    Gradient index lenses for flexural waves based on thickness variations 
    Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2014-08-11)
    This work presents a method for the realization of gradient index devices for flexural waves in thin plates. Unlike recent approaches based on phononic crystals, the present approach is based on the thickness-dependence ...

    Omnidirectional broadband acoustic absorber based on metamaterials 
    Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2012-04-06)
    We present the design, construction, and experimental characterization of the acoustic analogue of the so called photonic black-hole. The fabricated sample has cylindrical symmetry and consists of two parts, a shell that ...

    Transparent Gradient-Index Lens for Underwater Sound Based on Phase Advance 
    Martin, Theodore P.; Naify, C.J.; Skerritt, E.A.; Layman, C.N.; Nicholas, M.; Calvo, D.C.; Orris, Gregory J; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2015-09-15)
    Spatial gradients in a refractive index are used extensively in acoustic metamaterial applications to control wave propagation through phase delay. This study reports the design and experimental realization of an acoustic ...
