Abstract :
In this paper, a new structure with a perforated electrode design in free-flooded 33-mode ring transducer is proposed. The FEM is utilized to simulate the performance of the transducer, and several design parameters are optimized to achieve higher output power over a wider bandwidth. The tested performance of the manufactured transducers verify the validity of the design. The influence of different shape openings of transducer on its performance is also studied experimentally.
