Abstract: The features of the propagation of surface acoustic waves (SAW) in discretely layered structures solid – liquid – solid (SLS) are investigated. The conditions for the transformation of Rayleigh SAV into other types of waves that can be localized in a liquid layer, in sound-conducting plates as a leakage wave in the transverse wave mode having the character of a complex quantity are established. The values for the velocities of longitudinal and shear waves are obtained, related to the basic physical constants of the materials of the plates, liquid and the geometry of the layered structure. Possible applications of such structures in systems for various purposes as sensors or other electronic devices are indicated.
