ABSTRACT:
A photon triggered RF radiator that is composed of a photoconductive subste having a ground plane electrode on its bottom surface and a top surface electrode having separate sections to perform energy storage and energy radiation functions. The energy storage section has a bulk-type photoconductive switch position therein such that any energy stored in the energy storage section of the top surface electrode is instantaneously discharged through the substrate to the ground plane, thus causing a pulse of nanosecond pulsewidth dimension to radiate from the energy radiation section of the top surface electrode.
