Enhanced bandwidth multi1ayer transducers for imaging applications

The operating frequency of the presently used PZT or PZT composite ultrasound imaging transducers is determined by the half wavelength resonance or fundamental thickness mode of vibration. This resonance frequency together with the two quarter wavelength matching layers governs the bandwidth of the...
