A Novel Rectangular Waveguide with Double T-Septums (Short Paper)

A new rectangular waveguide with two T-shaped septums in place of solid rectangular ridges has been analyzed theoretically by the Ritz-Galerkin technique and is found to have superior cutoff and bandwidth characteristics of the dominant TE₁₀ mode compared to the conventional ridged guides. Numerical data are presented and compared with those of symmetric double-ridged guides with identical gap parameters.
