Surface and normal electroelastic shear waves in even-layered structures

Abstract

We construct the dispersion equations for surface and normal shear waves propagating in layered periodic structures consisting of alternating layers of piezoelectric and metal. We carry out a numerical analysis of the equations obtained in a wide range of variation of frequency. We describe the distinctive characteristics of dispersion spectra of surface and normal waves and their interrelation. We give the characteristic distributions of the amplitude walues of the mechanical displacements and stresses and the electric potential. Three figures. Bibliography: 7 titles.
