Abstract:

Broadband ultrasonic transducers using PVF2 piezoelectric plastics films, combining efficient transduction with extremely wide and uniform passbands, have been fabricated using very simple procedures without any critical tolerances. Frequency spectra of impulsed transducers using films of 25 and 50 micron thickness, centered at 10 and 5 MHz, respectively, are shown.
