P1E071-03. Optimal Design of a Wideband Multi-Mode Ring Transducer

The structure of an underwater multi-mode ring transducer was optimized to achieve the maximum bandwidth by means of the finite element method. The design scheme developed in this paper can be applied to optimize the structure of general underwater transducers to have a wider bandwidth at various operation frequencies. The designed transducer showed the -6-dB bandwidth of as much as 105%.
