Abstract :
A self-contained High Power Microwave (HPM) source with a peak power of 2.2 GW in the frequency range of 150-550 MHz is addressed. This source utilizes a coaxial electrodynamic structure, excited by two precisely synchronized high-pressure spark gaps. A Transverse Electromagnetic (TEM) horn antenna is used to direct and focus the HPM radiation. A field pattern converter, doubling as an impedance matching device, is used for matching the TEM-horn antenna to the electrodynamic structure. The field pattern converter and impedance matching device is integrated with a TEM-horn antenna. This design reduces the overall HPM source length (including antenna) to 165 cm and the diameter to 152 mm.
