| Abstract: | The matching layer is commonly used to expand the bandwidth of 1-3 piezocomposite transducers.But as time passes,the performance of matching layers will change,this change may cause performance instability of the transducer.By applying the concept of single-ended excitation to 1-3 piezocomposite material,a new piezocomposite structure,that is 1-1-3 piezocomposite material,was achieved.The finite element model of a 1-1-3 piezocomposite transducer was set up with ANSYS software and the structure of the transd... |
