Evanescent waves and deaf bands in sonic crystals

Romero García, Vicente; García Raffi, Luis Miguel; Sánchez Pérez, Juan Vicente (American Institute of Physics, 2011)

The properties of sonic crystals (SC) are theoretically investigated in this work by solving the inverse problem k(¿) using the extended plane wave expansion (EPWE). The solution of the resulting eigenvalue problem gives ...
Multi-resonant scatterers in sonic crystals: Locally multi-resonant acoustic metamaterial

Romero García, Vicente; Krynkin, A.; García-Raffi, L. M.; Umnova, O.; Sánchez Pérez, Juan Vicente (Elsevier, 2013-01-07)

An acoustic metamaterial made of a two-dimensional (2D) periodic array of multi-resonant acoustic scatterers is analyzed both experimentally and theoretically. The building blocks consist of a combination of elastic beams ...
Theoretical and experimental evidence of level repulsion states and evanescent modes in sonic crystal stubbed waveguides

Romero García, Vicente; VASSEUR, J.O; García-Raffi, L. M.; Hladky-Hennion, A.C. (IOP Publishing: Open Access Journals, 2012-02)

The complex band structures calculated using the extended plane wave expansion (EPWE) reveal the presence of evanescent modes in periodic systems, never predicted by the classical ω(kE) methods, providing novel interpretations ...
