Acoustic analogue of graphene: observation of Dirac cones in acoustic surface waves

Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2012-04-27)

We demonstrate the presence of Dirac cones in the dispersion relation of acoustic waves propagating on the surface of a plate of methyl methacrylate containing a honeycomb lattice of cylindrical boreholes. This structure ...
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 ...
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 ...
