Abstract : The patent describes a device for providing a continuously variable delay for successive pulses in a rf pulse train or for individual pulses by using the principle of variable velocity of acoustic waves in materials in which phonons soften. By employing a series of phonon softening devices, each contributes to the desired total delay while introducing a minimum amount of attenuation.
