On the use of aerogel as a soft acoustic metamaterial for airborne sound
Matthew D. Guild, Victor M. García-Chocano, José Sánchez-Dehesa +3
Soft acoustic metamaterials utilizing mesoporous structures have recently been proposed as a novel means for tuning the overall effective properties of the metamaterial and providi…
Acoustic metamaterial absorbers based on confined sonic crystals
Matthew D. Guild, Victor M. Garcia-Chocano, Weiwei Kan +1
Theoretical, numerical and experimental results examining thermoviscous losses in sonic crystals are presented in this work, enabling the fabrication and characterization of an aco…
Optimum control of broadband noise by barriers based on sonic crystals
Victor Manuel García-Chocano, José Sánchez-Dehesa
It is demonstrated that sonic crystals (periodic structures of sound scatterers) can be used to design acoustic barriers that attenuate efficiently broadband noise. Traffic noise i…
Multiple Scattering Formulation of Two Dimensional Acoustic and Electromagnetic Metamaterials
Daniel Torrent, José Sánchez-Dehesa
This work presents a multiple scattering formulation of two dimensional acoustic metamaterials. It is shown that in the low frequency limit multiple scattering allows us to define…
