    A hybrid method is presented for the rigorous analysis of horn
    antennas. The interior horn taper structure of arbitrary cross-section
    is described by the fast FE/mode-matching method combined with the
    generalized scattering matrix technique. For the exterior horn problem
    including the radiating aperture, an EFIE formulation is used where the
    eigen-vectors of the waveguide taper and the basis functions of Rao
    (1982) are chosen as basis functions. Results for a conical horn show
    good agreement with measurements. The flexibility of the presented
    method is demonstrated with the example of a conical ridged waveguide
