The problem of parameter inversion in an inhomogeneous medium was studied and a generalized ray approximation method to inverse the 2-D medium parameters is introduced in this paper. By using referential and perturbational variables, the medium parameters of the wave equation have been rewritten. By

We study the homogenization of the Euler system in a periodic porous medium (of period ฮต) by using the notion of two-scale convergence. At the limit, we recover a system which couples a cell problem with the macroscopic one.
