Effect of backing material on the transmitting response level and bandwidth of a wideband underwater transmitting transducer using 1-3 piezocomposite material. International Congress on Ultrasonics.

This paper investigates the possibility of incorporating rigid backing material into the transducer design to increase its stiffness and depth capability without adversely affecting its wide bandwidth and high transmitting levels. The transducer design under consideration uses 1-3 piezocomposite material, matching layer, coupling layer, stiff backing material (backing plates) and operates at 300 kHz with 200 kHz 6dB bandwidthenUltrasonicsTransducer designAcoustic matching layers1-3 piezocompositeWideband transmitterBacking materialUnderwater transmitting transducerInternational Congress on Ultrasonics 2009Conference PresentationNicolaides, K., Nortman, L., & Tapson, J.
