Relativistic Magnetron Priming by Loading the Resonators Through Dielectric Rods

A 3-D particle-in-cell code MAGIC 3-D has been used to study the output performance improvement of a relativistic magnetron through electric field priming by insertion of dielectric rods in the side resonators. The side resonators of the resonant structure have been loaded symmetrically at an angle of 120 ^° with a low-loss dielectric rod to implement the electric field priming. All the simulations have been performed for 2π-mode of operation on the well-known A6 relativistic magnetron. The results show that single 2π-mode operation with 43% improvement in radiated output power can be achieved through electric field priming by insertion of low-loss dielectric rods with optimized radius in the three-symmetrical side resonators.
