Acoustics of sorptive porous materials

R Venegas, C Boutin - Wave Motion, 2017 - Elsevier
Sound propagation in conventional rigid-frame porous materials is affected by the viscosity
of the saturating gas and the heat transfer between the gas and the solid frame. This paper …

Harnessing geometric frustration to form band gaps in acoustic channel lattices

P Wang, Y Zheng, MC Fernandes, Y Sun, K Xu… - Physical Review Letters, 2017 - APS
We demonstrate both numerically and experimentally that geometric frustration in two-
dimensional periodic acoustic networks consisting of arrays of narrow air channels can be …

Demonstration of slow sound propagation and acoustic transparency with a series of detuned resonators

A Santillán, SI Bozhevolnyi - Physical Review B, 2014 - APS
We present experimental results demonstrating the phenomenon of acoustic transparency
with a significant slowdown of sound propagation realized with a series of paired detuned …

Acoustics of permeo-elastic materials

R Venegas, C Boutin - Journal of Fluid Mechanics, 2017 - cambridge.org
In the dynamics of Biot poroelastic materials, the fluid flow is not affected by the deformation
of the solid elastic frame. In contrast, in permeable materials whose solid stiff frames have …

An efficient multiscale method for subwavelength transient analysis of acoustic metamaterials

R Liupekevicius… - Philosophical …, 2024 - royalsocietypublishing.org
A reduced-order homogenization framework is proposed, providing a macro-scale-enriched
continuum model for locally resonant acoustic metamaterials operating in the …

Nonlocal approach to energy bands in periodic lattices and emergence of electron mass enhancement

RA El-Nabulsi - Journal of Physics and Chemistry of Solids, 2018 - Elsevier
In this study, we analyze energy bands in periodic lattices based on the nonlocal-in-time
kinetic energy approach introduced recently by Suykens. We consider the electron dynamics …

Overall constitutive description of symmetric layered media based on scattering of oblique SH waves

AV Amirkhizi, V Alizadeh - Wave Motion, 2018 - Elsevier
This papers investigates the scattering of oblique shear horizontal (SH) waves off finite
periodic media made of elastic and viscoelastic layers. It further considers whether a Willis …
