## Abstract Using annular lenses in scanning acoustic microscopy, the attenuation coefficients for several materials were determined from the calculated __V__(__z__) interferenceβfree curves. The dependence of such coefficients on Rayleigh velocities as well as on operating frequencies was then inv
