Abstract
AN UNDERWATER SONAR TRANSDUCER WHICH COMBINES BOTH MAGNETOSTRICTION AND PIEZOELECTRICITY WILL BE STUDIES AND EVALUATED DURING PHASE I. THIS HYBRID TRANSDUCER HAS BEEN DESCRIBED IN U.S. PATENT 4,443,731 (BUTLER AND CLARK, HYBRID PIEZOELECTRIC AND MAGNETOSTRICTIVE ACOUSTIC WAVE TRANSDUCER) AND HAS THE POSSIBILITY OF PROVIDING CANCELLATION OF THE MOTION AT ONE END OF THE DEVICE AS WELL AS PROVIDING ELECTRICAL SELF TUNING. THE FEASIBILITY OF SUCH A TRANSDUCER YIELDING THESE USEFUL CHARACTERISTICS WILL BE STUDIED BY MEANS OF COMPUTER SIMULATION AND EVALUATED EXPERIMENTALLY BY SIMPLE MODELS DESIGNED TO TEST THE UNIQUE FEATURES OF THIS HYBRID TRANSDUCER.
