This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is suitable and effective as other methods for modeling of interconnecting lines in high- speed digital circuits. We mainly focus on designing of five-transmission lines interconnect in a single-layered dielectric medium and multimode waveguides. We computed the capacitance, inductance, and impedance matrices, and then we identify the potential distribution of the five-transmission lines interconnect in a single-layered dielectric medium and multimode waveguides.
