Propagation of surface transverse waves on a corrugated plate has been analysed. Results are presented for both thin and thick isotropic plates, showing that the dispersion curves for the lowest mode correspond in the second case to a semi-infinite substrate. A frequency equation is developed for planar resonators based on this type of wave propagation, applicable to both isotropic and rotated Y-cut trigonal plates.
