Fiber composite and PbTiO3 ceramic transducers performance are improved through innovative tuning techniques and optimized materials selection. The fiber composite transducers with center frequency around 40 MHz showed 6 dB bandwidth as high as 100% and round-trip insertion losses near -36 dB. Compared to fiber composite transducers, the PbTiO3 ceramic transducers can work at much higher frequencies (near 90 MHz). In a similar frequency range as fiber composite transducers, they showed improvement sensitivity as marked by an insertion loss around -24 dB. In addition, they still displayed good bandwidth as a result of electrical tuning.
