Characteristics of inhomogeneously filled double L-septa waveguides

Three types of inhomogeneous double L-septa guide (DLSG) produced by selective dielectric loading of the different regions are analyzed. The cutoff and bandwidth characteristics of these configurations are compared with the inhomogeneous T-septa guide and homogeneous DLSG. An optimum configuration with very large bandwidth emerges as a potential structure for practical implementation.<
