Abstract

Based on the finite number of vanes model, the high frequency characteristics of ridge-loaded helical slow-wave structure (SWS) are analyzed with field match method. This paper presents the sector equivalent method for loaded ridge and support rod, so the process of solution is simplified. The dispersion characteristics, interaction impedance and attenuation are derived for ridge-loaded helical SWS. The calculations are compared with the results of three-dimensional (3-D) electromagnetic (EM) simulation.
