IEEE Transactions on Microwave Theory and Techniques, 49 (1), 224-227.0018-94801557-9670https://hdl.handle.net/11441/99085This paper reports on a suitable formulation of the spectraldomain/integral-equation method for the quasi-TEM analysis of hybrid strip/slot-like planar lines. The free surface charge distribution is used as an unknown on the strip-like interface, whereas the electric field is used on the slot-like region. This formulation allows us to reduce the number of basis functions and makes possible a unified treatment of the problem. A single type of basis functions is used, leading to a quasi-analytical evaluation of the Galerkin matrix entries. The performance of the method is illustrated with a practical example structure useful for coupler design.application/pdf4 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Galerkin methodQuasi-tem analysisStrip/slot-like structuresinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/22.900016
