Research output: Contribution to journalConference article


A technique to vary the first resonance frequency of some widely used underwater acoustics transducers is presented. Theoretical investigations show that the frequency shift per DC field is linked to the ratio of the in-plane blocked force to the critical buckling load of the transducer. Calculations show that both significant frequency shifts per DC field and acceptable device coupling coefficients are achievable in practice.
