Abstract :
The theory of parametric excitation of acoustic waves in a bulk acoustic composite resonator has been developed. The mechanism of nonlinearity such as AC controlled boundary conditions is discussed. Numerical calculations revealed the possibility of parametric amplification of signals in the structures involved
