Abstract
A pulsed, beamless HPM oscillator is described. The oscillator operates in the frequency band of 120-600 MHz and has a peak RF power of 1.8 GW. The oscillator produces bursts of HPM pulses having a length of 8-10 ns, containing 3 individual pulses, each having rise times on the order of 200 ps. The oscillator uses a custom-designed dipole antenna array to focus and radiate the device's output RF energy. The referenced proprietary antenna array provides higher directivity in the operational frequency band and is specifically more efficient in the low-frequency portion of the radiated spectrum when compared to conventional Transverse Electric Mode (TEM) antennas having the same physical dimensions. The oscillator described above is a part of a phased multi HPM source system, capable of producing 12 GW of radiated RF power.
