Abstract

A technique for the measurement of velocity and strain of acoustic surface waves is proposed. It utilizes very thin vacuum deposited conductors in an applied magnetic field, which permits an unimpeded evaluation of the strain, velocity, and power of a propagating ultrasonic surface wave. The proposed method of measurement is simple and accurate. An example of a 10 MHz surface wave on glass is utilized to illustrate the measurement of particle velocity and power density of the longitudinal component of the wave.
