Recirculating Planar Magnetrons for High-Power High-Frequency Radiation Generation

We present designs and simulations of a new class of magnetron, the recirculating planar magnetron. This magnetron has numerous advantages as a high-power microwave generator, including larger cathode and anode area, fast start-up, and compact microwave extraction geometry. The following two geometr...

Description
Summary:We present designs and simulations of a new class of magnetron, the recirculating planar magnetron. This magnetron has numerous advantages as a high-power microwave generator, including larger cathode and anode area, fast start-up, and compact microwave extraction geometry. The following two geometries are demonstrated by electromagnetic particle-in-cell codes: 1) axial magnetic field with radial electric field and 2) radial magnetic field with axial electric field.
