Quantitative Analysis of Single-Surface Dielectric Multipactor Susceptibility with Dual Carrier Frequencies

This paper presents quantitative threshold analysis of multipactor breakdown on single dielectric surface initiated with an radio-frequency signal consisting of two carrier frequencies. The statistical modeling of multi-carrier multipactor on a dielectric is conducted for multipactor susceptibility chart and threshold analysis. On that basis, the effect of the relative phase and strength, and the frequency difference of two carrier frequencies on multipactor threshold are analyzed to achieve performance optimization. The results indicate that additional carrier frequency may increase power transmission capacity of high-power dielectric window.
