Temporal multiparticle Monte Carlo simulation of dual frequency single surface multipactor

Abstract

This work presents a multiparticle Monte Carlo simulation model in one dimension with adaptive time steps to investigate the time dependent physics of the single dielectric surface multipactor. Using this model, we study multipactor discharge on a dielectric with two carrier frequencies. We find that the saturation level and the oscillation pattern of the normal surface field with a parallel rf field of two carrier frequencies are different from those of single carrier frequency. Closed Lissajous curves are obtained to describe the temporal relationship between the fields normal and parallel to the surface in the ac saturation state.
