Wave propagation through saturated porous media

The homogenization procedure is applied to the problem of wave propagation in the biphasic mode in porous media saturated with a Newtonian fluid. The local problems corresponding to the solid and fluid phases have been solved separately for complex three-dimensional media. The effective rigidity tensor, some effective coefficients, the dynamic permeability, the celerities, and the attenuation of the three waves are systematically determined. The characteristic length Lambda was successfully used to gather results for the dynamic permeability as well as for the attenuation coefficients for all media.
