Multi-Frequency Recirculating Planar Magnetrons

Abstract

The Multi-Frequency Recirculating Planar Magnetron (MFRPM) is a type of Recirculating Planar Magnetron (RPM) designed for tunable or simultaneous oscillation at more than one primary frequency. Like the RPM, the MFRPM is a crossed-field, high power microwave (HPM) source that integrates the design advantages of the RPM with the added benefit of producing multiple frequencies using a single HPM device. Design of an L-S-band prototype is underway for a 0.2 T axial magnetic field and a -300 kV voltage pulse.
