Annotation
Parametric interaction between acoustic waves in layered periodic nonlinear media is considered. The conditions for synchronism between the signal wave and the pumping wave is investigated using numerical methods. Parametric interaction between the waves in a plexiglass - water periodic structure was observed experimentally. The local gain and the suppression of the signal were measured.
