  • Abstract
    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.
