A Ph.D. study. An ultrasonic transducer is shape-optimised in order to maximise the amplitude of the vibrating tip for a dry transducer and to maximise the radiated acoustic power for a submerged transducer. The axisymmetric ultrasonic transducer consists of 2 piezoelectric ceramic disks and two shape-optimised resonance rods and vibrates at resonance in longitudinal mode. For the submerged transducer, at the 2 tips, the transducer is in contact with water of infinite extent.
