Stealth and equiluminous materials for scattering cancellation and wave diffusion
S. Kuznetsova, J. -P. Groby, L. M. Garcia-Raffi +1
We report a procedure to design 2-dimensional acoustic structures with prescribed scattering properties. The structures are designed from targeted properties in the reciprocal spac…
Stealth acoustic materials
V. Romero-García, N. Lamothe, G. Theocharis +2
We report the experimental design of a 1D stealth acoustic material, namely a material that suppresses the acoustic scattering for a given set of incident wave vectors. The materia…
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…
Analytical model to predict the effect of a finite impedance surface on the propagation properties of a 2D Sonic Crystal
V. Romero-García, J. V. Sánchez-Pérez, L. M. Garcia-Raffi
The use of Sonic Crystals as environmental noise barriers has certain advantages from the acoustical and the constructive point of view with regard to conventional ones. One aspect…
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…
