Abstract
The WAF computation scheme is applied to numerical simulations of wave propagations in time-dependent heterogeneous media (liquids and active solids). The parametric phase conjugation of a wide band ultrasound pulse is considered. The supercritical dynamics of the acoustic field is described, in linear and non linear pumping conditions, for one-dimensional systems containing a parametrically active solid.
