Sh Waves

Theoretical study of uniaxial pressure influence on the propagation characteristics of Lamb and SH-waves in lithium niobate plate is carried out. Electromechanical coupling coefficients and controlling coefficients of the pressure influence on phase velocity are calculated in various directions. Transformation and hybridization of acoustic modes upon a pressure influence have been derived in details. PACS: 43.25.Fe; 43.35.Cg; 77.65.-j

Abstract The characteristic frequency equation for SH-wave propagation in an anisotropic, inhomogeneous-layered structure lying between two isotropic, homogeneous half-spaces is obtained by applying the Thomson-Haskell matrix method. A particular case is studied to analyze the effects of varying anisotropy on SH-wave dispersion. Numerical analysis is performed for a representative set of data to distinguish between the cases of increasing, uniform, and decreasing anisotropy coefficien in the medium.
