Wave focusing using symmetry matching in axisymmetric acoustic gradient index lenses
V. Romero-García, A. Cebrecos, R. Picó +3
The symmetry matching between the source and the lens results of fundamental interest for lensing applications. In this work we have modeled an axisymmetric gradient index (GRIN) l…
Level repulsion and evanescent waves in sonic crystals
V. Romero-García, J. O. Vasseur, A. C. Hladky-Hennion +2
This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solv…
Multi-resonant scatterers in Sonic Crystals: Locally Multi-resonant Acoustic Metamaterial
V. Romero-García, A. Krynkin, L. M. Garcia-Raffi +2
An acoustic metamaterial made of a two-dimensional (2D) periodic array of multi-resonant acoustic scatterers is analysed in this paper. The building blocks consist of a combination…
