One possible way to emit THz waves is to pass short electron bunch through a waveguide structure loaded with dielectric. Previously we considered the extraction of radiation from the open end of the waveguide with dielectric loading in both approximate and rigorous formulation. We also developed a rigorous approach based on mode-matching technique and modified residue-calculus technique for the case when the waveguide with dielectric is co-axial with infinite waveguide with greater radius. The study presented is devoted to the case when the dielectric loaded waveguide has a flange and enclosed into another waveguide with a greater radius. The case of the flanged waveguide in the unbounded vacuum space can be described as the limiting case of the problem under consideration. We perform analytical calculation (based on mode-matching technique and modified residue-calculus technique) and direct numerical simulation.
