Abstract
In this paper, the existence and behavior of electro-elastic shear waves propagating in a two-layer waveguide consisting of a piezoelectric (tetragonal class 4mm or hexagonal class 6mm) and conductive layers that have different thicknesses - h 1 , h 2 are investigated. The mathematical boundary-value problem is formulated. Distribution of the electro-elastic wave fields across the thickness of the waveguide, as well as, the characteristic equation of electro-elastic shear waves in respect to the phase velocity are obtained. In depending both of the physical-mechanical characteristics of foreign materials and the relative thickness of layers in layered system, the existence of localization of a short electro-elastic shear waves in a layered waveguide is analyses. The structure and phase behavior of localized surface or volumetric surface waves are studied. The numerical and graphical dispersion analysis of wave propagation is realized.
