Description
Summary:The development of piezoelectric transducers based on periodically poled ferroelectrics domains is investigated. Optical quality Z-cut LiNbO 3 wafers have been used for the fabrication of test devices operating in the range 7-70 MHz. The fabrication process is detailed and characterization results are reported. A very good agreement between theoretical predictions achieved by periodic finite element analysis and experiments is observed, allowing for a precise identification of the excited modes
