    Multiple scattering formulation of two-dimensional acoustic and electromagnetic metamaterials 
    Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (IOP Publishing: Open Access Journals, 2011-09-09)
    A multiple scattering formulation of two-dimensional (2D) acoustic metamaterials is presented. This approach is comprehensive and can lead to frequency-dependent effective parameters (scalar bulk modulus and tensorial mass ...

    Sound focusing by gradient index sonic lenses 
    Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics (AIP), 2010-09-06)
    Gradient index sonic lenses based on two-dimensional sonic crystals are here designed, fabricated, and characterized. The index-gradient is achieved in these type of flat lenses by a gradual modification of the sonic crystal ...
