IEEE Transactions on Microwave Theory and Techniques, 46 (11), 1801-1806.0018-94801557-9670https://hdl.handle.net/11441/99499This paper reports on an enhanced implementation of the spectral-domain analysis (SDA) of boxed multistrip or multislot transmission lines embedded in a layered medium, including biaxial materials. Very high numerical efficiency is attained by a suitable basis and mixed SDA and spatial-domain technique to calculate the entries of the Galerkin matrix. Convergence properties of SDA are drastically improved, making it competitive with other analytical techniques [such as regular singular integral equation (RSIE)]. The method allows quick and accurate computation of current/field distributions.application/pdf6 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Analytical methodsPlanar linesSpectral-domain analysisinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/22.7345886702457
