This paper investigates the pressure eld generated at the bottom of a high-contrast randomly layered slab by an acoustical pulse emitted at the surface of the slab. This analysis takes place in the framework introduced by Asch, Kohler, Papanicolaou, Postel and White 1] where the incident pulse wave length is long compared to the correlation length of the(More)
The aim of this contribution is to present recent results obtained at the "Centre de Math ematiques Appliqu ees de l' Ecole Polytechnique" by the group working on waves in random media (These results are based on various generalizations of classical diiusion-approximation results. In the rst section we study the spreading of an acoustic pulse travelling(More)
