Abstract
A pulsed power supply for providing power to a piezoelectric crystal. The power supply provides power to the piezoelectric crystal causing contraction of the crystal. Upon reaching a predetermined degree of contraction, the electrical voltage form the power supply is removed from the piezoelectric crystal by creating a short-circuit between the power supply and the crystal. Removal of electrical voltage from the crystal causes the immediate expansion of the crystal and a resulting energy wave.
