Abstract: A tunable frequency transmission line pulse forming network circuit for forming a waveform having a spectral content. The pulse forming network circuit comprises a dielectric material; a ground section; a stepped shaped charged section, with the charged section having a plurality of stages including a first stage; a power supply coupled to the pulse forming network circuit for charging the pulse forming network circuit; a switch coupled to the pulse forming network circuit for periodically discharging the pulse forming network circuit; and an antenna coupled to the pulse forming network circuit for propagating a high-power microwave signal from the pulse forming network circuit into the environment. At least the first stage of pulse forming network circuit has one of a tunable magnetic material and a nonlinear magnetic which facilitates adjusting the waveform and the spectral content of the waveform emitted by the pulse forming network circuit into the surrounding environment.

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.

Abstract: A system and method for generating high power pulses including a photoconductive semiconductor switch (PCSS), a laser for triggering the PCSS and a bipolar pulse generator coupled to the PCSS. The bipolar pulse generator is activated when the PCSS is triggered. A bipolar pulse is generated by the activated bipolar pulse generator. A modulator unit modulates the bipolar pulse to create a modulated bipolar pulse. The modulator unit is a nonlinear transmission line (NLTL).
