Popis: The study of the features of the propagation of surface acoustic waves (SAWs) is based on the solution of boundary value problems of electroelasticity for media with an inhomogeneous coating, the construction of the Green's functions of the medium and the analysis of its dispersion properties. For the cases of electrically open and electrically short-circuited surfaces, the influence of the ratio of the physical parameters of the coating materials, the localization region and the size of the transition zone of one material to another on the features of the propagation of Rayleigh waves is investigated. The results obtained in this work are useful for understanding dynamic processes in piezoelectric structures with an inhomogeneous coating in order to optimize and create new structures and devices based on SAWs with high performance characteristics.
