Abstract

We experimentally and theoretically studied an exact measurement model for attenuation of leaky surface acoustic waves (LSAWs) using the line-focus-beam ultrasonic-materialcharacterization (LFB-UMC) system. We measured the LSAW propagation characteristics (viz., phase velocity and attenuation) for two specimens of synthetic silica (SiO2) glass and borosilicate (Pyrex) glass at 225 MHz. We detected acoustic loss of LSAWs due to the acoustic absorption effect for the Pyrex glass by calibrating the measurement results with reference to those of the SiO2 glass.
