Abstract
Investigations into the characteristics of water-coupled ultrasonic capacitance transducers have been performed for a range of transducer configurations. The radiated fields have been scanned in water using a miniature hydrophone detector, and the results compared to theory based on a plane piston approach. Additionally, the transducer has been used in pulse-echo mode and a C-scan performed to image an artificial defect in a Plexiglas plate
