Finite-element analysis of T-septum waveguide structures

The cutoff wavelength, the bandwidth and the plots of field of hollow and dielectric-loaded T-septum waveguide structures Crectangular T-septum waveguides with specific configurations, ridged and channel waveguides with a T-shaped find are computed by finite element method. The ways of improving the characteristics like increasing bandwidth, a minimization of sizes and so on, are analysed.
