![عکس صفحه اول مقاله: Surface electro-elastic Love waves in a layered structure with a piezoelectric substrate and a dielectric layer Surface electro-elastic Love waves in a layered structure with a piezoelectric substrate and a dielectric layer](/preview/png/279355.png)
The existence and behaviour of electro-elastic surface Love waves in a structure consisting of a piezoelectric substrate of crystal classe 6, 4, 6 mm, 4 mm, 622 or 422, an elastic layer and a dielectric medium is considered. The mathematical model obtained includes all the above crystal classes, i.e. the surface wave problems related to all these classes are presented in a single mathematical model. The dispersion equation for the existence of Love surface waves with respect to phase velocity is obtained. A detailed investigation of the electromechanical coupling coefficient is carried out depending on the dielectric and piezoelectric parameters of the problem. Geometrical investigation of the solutions of the dispersion equation is carried out.
