On the Rayleigh wave propagation along the boundary of an inhomogeneous anisotropic porous Biot medium

The Rayleigh wave propagation along the traction-free boundary of an inhomogeneous anisotropic fluid-saturated porous solid (a Biot medium) is considered. Analytic expressions for the amplitude and the Berry phase of this oscillation are obtained. These analytic expressions are valid for the arbitrary shape of the porous solid. Bibl. 4 titles.
