Abstract :
Interaction of acoustic wave harmonics in a solid layer with a one-dimensional periodically irregular boundary is studied in detail. Resonances between different modes of the harmonics has been predicted in such a structure. Due to the resonances the acoustic spectrum of the layer takes miniband character with densely spaced forbidden gaps
