Abstract

In this contribution we have presented a new metallo-dielectric EBG waveguide. The initial concept is based on Bragg fiber, which cross section is usually very large in terms of the wavelength. To reduce the waveguide dimensions and make it feasible at THz frequencies, we use a combination of a metallic and a dielectric waveguide. Standard resonant geometries will have high bend coupling between the TE01 and EH11 modes, thus reducing the losses introduced by the bend. Here we present two ways of optimizing the waveguide structure to break the degeneracy between these modes. One considers the periodicity along p and the other along Z. The results can be extended to structures with two or three periods to reduce the metallic losses. These structures will have an overall propagation and bend loss lower than an overmoded circular waveguide working on the TE11 mode.
