Surface waves in thin-film coatings on piezoelectric half-space and on piezoelectric plate belonging to the (622) crystal class

Love-type surface waves in thin-film coatings on a piezoelectric half-space of the (622) crystal class are studied. Silver and gold coatings are used on the piezoelectric half-space, and numerical results are obtained for the relationship between the velocity and the wave number. Surface waves by thin-film coatings on both sides of an infinite piezoelectric plate of the (622) crystal class are also studied. The dispersion equation has been solved for a given velocity to obtain the wave number numerically.
