Abstract
In the article the existence and behaviour of electroelastic Love waves in three-layered system of a piezoelectric substrate of classes 6, 4, 6mm, 4mm and attached to her two isotropic layers (conductor-dielectric, conductor-conductor) of any thickness is investigated, depending on the physicomechanical characteristics of layered system and relative thicknesses of layers. The characteristic equation of a required surface wave is investigated in case of a basic soft layer. The research is based on properties of the electromechanical factor of surface wave given in the work [1-5]. Existence of a Love wave of a gap type caused by extremely piezoelectric effect in particular is shown. The structure and behavior of modes of Love waves are investigated. The qualitative diagrams of “dispersive” curves of modes of Love waves are given . The relation between electroelastic Love waves, pure-elastic Love waves, and Bleustein-Gulyaev waves is discussed.
