Abstract :
Effect of acoustic loss in solids on depths of dips in V(z) curves obtained by reflection acoustic microscopy was calculated. The results were in good agreement with the observed V(z) curves of steels. The applicability and limitations of measuring attenuation of surface acoustic waves from V(z) curves are discussed.
