Abstract

This paper is concerned with the properties of SH (Shear Horizontal) wave in two-layer piezoelectric plate with 180° domain wall. Besides the dispersion equation of the symmetry vibration mode, that of the asymmetry vibration mode has been obtained. It is concluded that the asymmetric vibration mode has obviously dispersion properties under the condition of metalized surface. The distribution of the displacement u and electric potentials Φ for asymmetric mode have been analyzed. The properties of the asymmetric mode are affected by the change of the surface electric condition that lead to the change of the surface charge distribution
