Propagation in periodically loaded corrugated waveguides

The analysis and characterization of corrugated periodic structures in dielectric loaded waveguides are presented. The Floquet theorem and mode-matching techniques are used to perform the analysis. The characteristic equation, which gives the dispersion relation for the periodic structure, is derived. Phase and group velocities of waves on these periodic structures are then obtained from the dispersion curves. These results have potential applications as slow wave structures for traveling-wave tubes and possible filtering structures at millimeter-wave frequencies.<
