Dispersion in unilateral fin lines with two dielectric layers

Using an efficient method of analysis, the dispersion characteristics in new unilateral fin-line structures have been obtained. It consists of using an equivalent transmission line theory in the spectral domain of the Fourier transform with the moment method. The analysis is general and may be applied to a variety of structures. Numerical results are obtained for unilateral fin lines with one and two dielectric layers located symmetrically or asymmetrically in the E-plane of the waveguide.
