Rayleigh Waves: Properties and Applications

This lecture explores Rayleigh waves, which are surface acoustic waves concentrated near the surface of an elastic solid. The equations of motion, longitudinal and transverse acoustic fields, and the dispersion equation are discussed. The lecture delves into the vector form of the motion equation, the representation of plane waves, and the properties of Rayleigh waves in isotropic elastic media. The presentation covers the boundary conditions, dispersion equation, and power flow in Rayleigh waves. The lecture concludes with a numerical example and problems for further exploration.
