Particle-In-Cell (PIC) simulation of Spatial-Harmonic Magnetron (SHM)

Abstract

RF Vacuum Electronic Devices (RF VEDs) have been the most promising milestones for radio-wave and microwave generation at high power and high frequencies for decades. Spatial Harmonic magnetrons (SHMs) with cold secondary emission cathodes have proved to be an efficient solution to the viability of magnetrons at high frequency. The paper presents a 3-D Particle in Cell (PIC) simulation of a D-Band (140 GHz) SHM using CST particle studio (CST-PS).
