    Diseño y caracterización de metamateriales acústicos basados en guías de onda 
    Graciá Salgado, Rogelio (Universitat Politècnica de València, 2014-07-14)
    En la realización de este trabajo se obtendrán las expresiones analíticas que permiten describir las propiedades acústicas de una red de elementos dispersivos en el interior de una guía de ondas, permitiendo así, obtener ...

    Double-negative acoustic metamaterials based on quasi-two-dimensional fluid-like shells 
    Graciá Salgado, Rogelio; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (IOP Publishing: Open Access Journals, 2012-10-31)
    A structured cylindrical scatterer with low-frequency resonances in both the effective bulk modulus and the dynamical mass density is designed and characterized. The proposed scattering unit is made of a rigid cylinder ...

    Negative mass density and ρ-near-zero quasi-two-dimensional metamaterials: Design and applications 
    Graciá Salgado, Rogelio; García Chocano, Víctor Manuel; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2013-12)
    We report the design and the characterization of artificial structures made of periodical distributions of structured cylindrical scatterers embedded in a two-dimensional (2D) waveguide. For certain values of their geometrical ...

    Quasi-two-dimensional acoustic metamaterial with negative bulk modulus 
    García Chocano, Víctor Manuel; Graciá Salgado, Rogelio; Torrent Martí, Daniel; Cervera Moreno, Francisco Salvador; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2012-05-14)
    We present the experimental realization and characterization of an acoustic metamaterial with negative bulk modulus. The metamaterial consists of a two-dimensional array of cylindrical cavities, and the bulk modulus is ...
