Surface Acoustic Waves: Bleustein-Gulyaev Waves

This lecture covers Bleustein-Gulyaev waves, a type of surface acoustic wave with horizontally polarized shear components. It explains the propagation of these waves in different media, including isotropic and piezoelectric materials. The lecture discusses the dispersion equations, mechanical displacement formulas, and the impact of piezoelectric properties on wave behavior. It also explores Love waves, leaky surface acoustic waves, and surface skimming bulk waves. The instructor delves into the physical interpretations, dispersion characteristics, and practical applications of these waves in mobile communication devices.
