The excitation, distribution, and interaction of surface acoustic waves (SAW) and pseudo surface acoustic waves (PSAW) in a X-cut lithium niobate substrates were investigated. The resonant excitation frequencies, the wave distribution velocities and the dispersion characteristics were determined for each of the wave types. The influence of the interdigital transducer (IDT) material on the excitation efficiency and the interaction between investigated wave types was found out. The interdigital transducer material and configuration requirements for integrated acousto-optic devices were determined.
