Numerical simulation of oscillating magnetrons

Abstract

The temporal evolution of the current, voltage, and rf fields in magnetron-type devices has been simulated numerically by a two-dimensional, electromagnetic, fully relativistic particle-in-cell code. The simulation allows for the complete geometry of the anode vane structure, space-charge-limited cathode emission, and the external power source. The code has been applied to magnetrons operating in the relativistic energy regime.
