This lecture delves into the topic of Rayleigh waves in piezoelectric crystals, focusing on the surface acoustic waves (SAW) and their propagation in anisotropic materials. It covers the main equations for acoustic and electric fields, plane waves in anisotropic crystals, and the unique characteristics of Rayleigh waves in piezoelectrics. The lecture explores the influence of electrodes on these waves, the emergence of Bleustein-Gulyaev waves in special symmetry cases, and the differences between Rayleigh waves and BGW. It also discusses the slowness curves in isotropic and anisotropic media, providing insights into wave propagation and reflections in crystals.
