摘要：
Composite piezoelectric materials are of increasing importance in transducer technology. Recent research work is focused on ceramic-polymer composites for medical and material diagnosis. The present paper deals with the dynamic behaviour of broadband composite transducers, with particular emphasis on sound field properties affected by lateral resonance effects. Besides admittance and transfer function measurements a high-resolution acousto-optic technique is also used which makes detailed insight into the sound field structure possible.
