The purpose of this paper is to explain the subharmonic generation of waves (SWG) in piezoelectric plates with Cantor-like structure. We show that SWG is due to a nonlinear superposition of cnoidal waves in both phonon and fracton vibration regimes. We propose an original inverse method based on a genetic algorithm for an optimal identification of system parameters by inversion of the vibrational data.
