Multiple scattering from randomly distributed fluid spheres in a poroelastic medium

Résumé

A longitudinal wave (fast or slow) or a transverse wave incident on a spherical inhomogeneity localized in a fluid-saturated poro-elastic medium causes the scattering by this inhomogeneity of three waves (fast, slow and transverse). After having dealt with the problem of scattering by an inhomogeneity, we examine that of the multiple scattering by a random distribution of spheres of equal radii, in the low frequency regime known as the Rayleigh regime. In this context, the influence on certain effective quantities (wave numbers, densities and modules) of the poro-elastic matrix/fluid cavities continuity conditions is highlighted. Some analytical and numerical results will be discussed.
