Theoretical study on the influence of uniaxial pressure on the propagation characteristics of Lamb and SH-waves in lithium niobate plate includes calculations of electromechanical coupling coefficients and controlling coefficients of phase velocity in various directions, as well as detailed derivation of transformation and hybridization of acoustic modes under pressure influence.
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.
