Abstract
Combines the theoretical analysis and practical design of an electrostatic transducer capable of detecting, in metal specimens, surface (Rayleigh) waves with displacement amplitudes less than 10-8 cm. This form of transducer is offered as an alternative to electromagnetic acoustic transducers as a means of receiving ultrasonic Lamb and surface waves in nondestructive test applications. It also provides a means of calibrating the amplitudes of ultrasonic surface waves generated by any means.Keywords
