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.

Sound absorption and reflection from a resonant metasurface : homogenization model with experimental validation (2017)

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...
