Abstract: A system and method utilizing thyristor-based Photo-Conductive Semiconductor Switches (PCSS) for short pulse switching in high power microwave and/or broadband electromagnetic pulse generation is disclosed. The PCSS consists of thyristor-type NPNP structure having multiple emitter regions enclosed by the base region and multiple emitter shorts to divert leakage currents for voltage holding. The PCSS also includes an optical aperture comprised of patterned metallic grids for light illumination and current collection. The device structure is so constructed that there is only one single bevel around the peripheral. The thyristor-based PCSS have dual polarities of voltage blocking and have better efficiency for light requirement to operate at longer pulse duration compared to diode-based and bulk-semiconductor-based PCSS.

Abstract: A steerable high-power microwave beam array includes an optical sub-system comprising a laser and an optical time delay unit and a parallel set of RF time delay units. The optical system and/or the RF delay subsystem are utilized to precisely delay the pulses from the microwave antenna elements to provide steerable beam forming.
