Abstract
Abstract A variable interval electromagnetic pulse train generator having a semiconductor substrate on which is mounted on one surface thereof a plurality of spaced apart electrodes and on another surface thereof an electrode base plate. A voltage source is connected to each of the plurality of spaced apart electrodes while the space between electrodes have optical pulses directed thereon. By controlling the voltage applied to the electrodes and the optical pulses directed between electrodes the pulse train generator is capable of emitting a series of variable, spaced apart electromagnetic pulses.
