The ultrasonic attenuation of polyvinylidene fluoride (PVF2) piezoelectric films has been measured at high frequencies (150–450 MHz). It was observed that the propagation loss varies linearly with frequency. The ultrasonic Q of the PVF2 films is constant and equal to 19. It is thus possible to use PVF2 films for high-frequency applications.
