Abstract
A new method of direct attenuation measurement of leaky waves is proposed through V(z) curves obtained by the line-focus-beam acoustic microscope, simultaneously giving the corresponding wave velocity. Experiments are demonstrated for fused quartz with an acoustic line-focus-beam sapphire lens of 1.0 mm radius at 226.3 MHz. The attenuation measurement is achieved with a sufficient accuracy of about 5% as compared with the calculated value.
