On the ray method for the Biot medium

This work is devoted to investigation of wave propagation in the Biot porous medium, which consists of elastic and fluid phases. The space-time ray decay of the solutions of dynamical equations for the Biot medium is constructed (in anisotropic inhomogeneous case). In inhomogeneous isotropic case the Rytov law analogue is deduced like in elastic theory. Bibl. – 3 titles.
