Abstract

A new type of multi-beam slow-wave structure used in millimeter wave band was presented in this paper. The characteristics of the slow-wave circuit were analyzed and the equivalent circuit was obtained. Using numerical simulation software, the model of slow-wave structure was established, meanwhile, frequency dispersion and coupling impedance were simulated. The results of numerical simulation show that the type of multi-beam slow-wave structure has the characteristics of good dispersion, high coupling impedance and high effective interaction, so it can be widely used in millimeter wave traveling wave tube with high power.
