A nonscanning reflection acoustic microscope with a line-focus beam is applied to investigate propagation characteristics of leaky SAWs on water/LiNbO3 boundary. Experiments are performed for both cases without and with an Al-film shorting plane at the boundary of water/Y-cut-LiNbO3. The effect of water ‘loading’ on LiNbO3 is successfully detected.
