Abstract:

Misalignment of the ferroelectric ceramic transducers in a width-sheer mode ultrasonic delay line is a recognized source of signal attenuation. An evaluation is made of its effect on a 200-microsecond line operating at a center frequency of 10 Mc. Using an aluminum transmission line and controlled localized heating to produce controllable amounts of mislaignment, experimental values were obtained. A simplified analysis provides a theoretical curve which agrees with the experimental values and, in particular, matches well for the smaller degree of misalignment which is of practical interest.
