Rectangular Waveguide with T-Shaped Septa

Recently, a new rectangular waveguide with two T-shaped septa has heen proposed by the authors as a superior alternative to conventional ridged guide. Here, numerical data on the cutoff and band-width characteristics of the dominant TE/sub 10/ mode of rectangular waveguide with a single T-septum are presented and compared with those of single-ridged guides. The gap impedances of both the double and single T-septum guides are also determined as functions of gap parameters.
