Abstract
Abstract A piezoelectric composite transducer was developed in this study to improve the bandwidth and beamwidth of the high-frequency transducer. The piezocomposite was designed as arc-shaped to expand the beamwidth, and the matching layer technique was adopted to increase the bandwidth. The directivity function was obtained by the acoustic field theory. The parameters of the matching layer were also calculated using the quarter-wavelength model. Then, a novel preparation process of arc 1–3 piezoelectric composite was given in detail. Finally, the arc 1–3 piezocomposite and transducer were prepared and tested. The bandwidth and beamwidth of the transducer reach 100 kHz and 123°, respectively. Experimental results show that the designed transducer realizes the aims of broadband and wide-beam.
期刊介绍：
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
