Abstract :
This report deals with the investigation of the SAW velocity dispersion and determination of the coefficients of SAW transformation into bulk acoustic waves on the basis of experimental and theoretical analysis of the SAW propagation in reflective gratings. The reflective gratings consist of the irregular sequence of grooves on the surface of the lithium niobate YZ-cut
