Abstract :
A ceramic-metal composite electroacoustic transducer has been developed for use as an underwater projector or receiver. Its resonance frequency ranges from 10 kHz to 40 kHz and its effective coupling coefficient is around 20%. Finite element analysis has been performed to ascertain how the transducer dimensions and the materials that comprise it effect aforementioned parameters
