metadata.value: An approach to studying the influence of initial mechanical stresses and an electrostatic
  field on the structure and behavior of Rayleigh waves in piezoelectric media with nonhomogeneous
  coatings is proposed. This paper considers two-component coatings made of
  functionally graded piezoelectric material with high-speed (the speed of the shear wave
  inclusion is greater than the speed of the shear wave in the substrate) or low-speed (the
  speed of the shear wave inclusion is less than the speed of the shear wave in the substrate)
  inclusions. The initially deformed state of the coating is induced by the separate or combined
  action of initial mechanical stresses and an external electrostatic field. The influence of the
  type of non-homogeneity and the nature of initial mechanical stresses in the presence or
  absence of an initial electrostatic field on the features of Rayleigh wave propagation for
  problems with an electrically open or shorted surface is studied. It is established that the
  presence of a low-intensity initial electrostatic field only slightly affects the action of initial
  mechanical stresses depending on its direction. The presence of a high-intensity electrostatic
  field leads to additional deformation of the material, significant changes in the speeds of
  PAV modes, and substantial changes in the structure of the surface wave field. The obtained
  results are presented in dimensionless parameters and may be of practical interest in the
  development, design, and optimization of new materials for micro- and nanoscale devices
  and devices on Rayleigh surface acoustic waves with high performance characteristics.
