Study of output performance of partially dielectric loaded A6 relativistic magnetron

Abstract

A three dimensional particle-in-cell code MAGIC-3D is used to examine the output performance of a partially dielectric loaded A6 relativistic magnetron. The side resonators of the resonant structure are loaded symmetrically at angle of 120° with low-loss dielectric material. The simulation of dielectric loaded A6 relativistic magnetron is performed for 2π -mode of operation. The formation of six electron spokes in the oscillation region confirms 2π-mode oscillation of a six vane relativistic magnetron. The results indicate single 2π-mode operation with improved radiated output power of 620 MW with relatively low start-up time in comparison to unfilled resonant structure. A power increase of 40% is found in case of partially filled dielectric resonator in comparison to unfilled dielectric resonators. © 2012 IEEE.
