Enhanced 3D-printed holographic acoustic lens for aberration correction of single-element transcranial focused ultrasound
Marcelino Ferri, JM Bravo, Javier Redondo +1
The correction of the aberration of transcranial focused ultrasounds is a relevant issue for enhancing various non-invasive medical treatments. Emission through multi-element phase…
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…
Design techniques for superposition of acoustic bandgaps using fractal geometries
S. Castiñeira-Ibáñez, V. Romero-García, J. V. Sánchez-Pérez +1
Research into properties of heterogeneous artificial materials, consisting of arrangements of rigid scatterers embedded in a medium with different elastic properties, has been inte…
Evanescent modes in Sonic Crystals: Complex relation dispersion and supercell approximation
V. Romero-García, J. V. Sánchez-Pérez, L. M. Garcia-Raffi
Evanescent modes in complete sonic crystals (SC) and SC with point defects are reported both theoretically and experimentally in this paper. Plane wave expansion (PWE) and, in gene…
