Abstract :
An approximation for the Green´s function used to analyse surface-acoustic-wave generation on piezoelectrics is proposed. It allows for the effect of the leaky surface wave. The result is useful for calculating the reflectivity of, and velocity change due to, thin metal dots on Y-cut LiNbO3.
