Study of Two-Frequency RF Field Induced Two-Surface Multipactor

Multipactor is a nonlinear AC discharge phenomenon occurring in RF systems and system components in which a high frequency RF field creates an electron avalanche sustained through secondary electron emission [1] from metallic or dielectric surfaces. This work presents a study of two-surface multipactor discharge induced by two-frequency RF fields. We employ Monte Carlo simulations [2] , [3] and Computer Simulation Technology (CST) [4] to examine the effects of the relative strength and phase of the second carrier mode on multipactor susceptibility and time dependent physics [3] .
