Abstract

PURPOSE: To prevent drop of detecting sensitivity even for high frequency AE waves without reducing the diameter of transducer, eliminating the direction dependence of detecting sensitivity, by providing a protrusion on an acousto-electric transducer and receiving vibrating waves through the same.
