Interferometric method of determining the refraction index of two-dimensional sonic crystals

Romero García, Vicente; Fuster García, Elíes; García-Raffi, L. M.; Sánchez Pérez, Juan Vicente; Uris Martínez, Antonio (American Physical Society, 2007)

[EN] Sonic crystals are defined as materials consisting of periodic distributions of acoustic scatterers in another medium with different elastic properties. These materials present two main acoustical features: they present ...
Negative refraction and energy funneling by hyperbolic materials : an experimental demonstration in acoustics

García Chocano, Víctor Manuel; Christensen, Johan; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2014-04-10)

This Letter reports the design, fabrication, and experimental characterization of hyperbolic materials showing negative refraction and energy funneling of airborne sound. Negative refraction is demonstrated using a stack ...
