Abstract

An annular array with equal area elements has been fabricated and tested. The elements are made from a novel fine-grain lead titanate which was micromachined using a laser to form the kerfs. Resonance methods showed the lead titanate exhibited electromechanical properties similar to bulk materials, including a thickness coupling k_t of 0.49 and low permittivity (ε^s₃₃/ε₀ = 178). An average center frequency of 53 MHz with 40% bandwidth was obtained across all the elements. Cross-talk levels were below -20 dB in water. Good agreement was obtained between the measured results and a finite element model.
