Abstract
A multidomain two-dimensional periodically poled ferroelectric plate vibrator is reported for the first time. The theoretical calculations, computer simulations by the Finite Element Method and experimental data from the lithium tantalite samples reveal a domain acousto-electric resonance. A polarization inversion in a y-rotated cut of a ferroelectric chip is firstly done. The acousto-electric characteristics of the vibrator are calculated and measured.
