Acoustic waves in gas-filled structured porous media: Asymptotic tortuosity/compliability and characteristic-lengths reevaluated to incorporate the influence of spatial dispersion
This study extends efforts to incorporate spatial dispersion into Biot-Allard’s theory, with a focus on poroelastic media with intricate microgeometries where spatial dispersion effects play a significant role. While preserving Biot’s small-scale quasi-“en-bloc” frame motion to keep the structure of...
