ABSTRACT:
A phase modulator is provided with supports attached to the resonating element. The supports have a length which is an odd number of quarter wavelengths of a longitudinal acoustic wave excited in the supports by the resonating element. As such, a longitudinal acoustic wave excited at the resonating element end of the support travels along the support, is reflected at the other end of the support, and returns in opposite phase to that of the excited wave, thereby causing a null in longitudinal amplitude of the wave and reducing the damping of the resonating element.
