Abstract
A new realization of a cylindrical meta-waveguide is proposed. The guide is a metallic cylinder loaded azimuthally with conducting rods short circuited to the outer cylinder. It can be simplified to a planar periodically cascaded coupled lines. However, the actual circuit is described in cylindrical coordinates as screw or helically periodic structure. The dispersion relation was obtained from the circuit model and from the actual structure using EM simulation, with a good agreement between both. An 8-cell structure was simulated to show the overall guide transmission characteristic. The major advantage of this new guide is that it does not contain any dielectrics, which makes it favorable in applications involving electron beams such as Backward Wave Oscillator BWO, Gyrotron BWO, and Cherenkov backward wave detector.
