Journal Article
Venegas, R., Boutin, C., & Umnova, O. (2017). Acoustics of multiscale sorptive porous materials. Physics of Fluids, 29(8), 082006. https://doi.org/10.1063/1.4999053

This paper investigates sound propagation in multiscale rigid-frame porous materials that support mass transfer processes, such as sorption and different types of diffusion, in addition to the usual visco-thermo-inertial interactions. The two-scale a... Read More about Acoustics of multiscale sorptive porous materials.

Influence of diffusion and sorption on sound propagation in multiscale porous materials (2017)
Presentation / Conference
Venegas, R., Boutin, C., & Umnova, O. (2017, July). Influence of diffusion and sorption on sound propagation in multiscale porous materials. Presented at 6th Biot Conference on Poromechanics, Paris, France

This paper investigates sound propagation in multiscale sorptive porous materials saturated with a pure gas. An example of this type of materials is a packing of porous grains where a mesoscopic, microscopic, and nanoscopic scale can be identified. T...

Sound absorption and reflection from a resonant metasurface : homogenization model with experimental validation (2017)
Journal Article
Schwan, L., Umnova, O., & Boutin, C. (2017). Sound absorption and reflection from a resonant metasurface : homogenization model with experimental validation. Wave Motion, 72, 154-172. https://doi.org/10.1016/j.wavemoti.2017.02.004

Efficient manipulation of sound waves by some resonant acoustic metasurface designs has recently been reported in the literature. This paper presents a general theoretical framework for the description of sound wave interaction with the resonant meta...
