Finite Element Analysis of Five-Transmission Lines Embedded in Four-Layered Dielectric Media

Development of very high speed integrated circuits is currently of great interests for today’s technologies. This paper presents the quasi-TEM approach for the accurate parameters extraction of multiconductor transmission lines interconnect in four-layered dielectric region using the finite element method (FEM). We illustrate that FEM is accurate and effective for modeling multilayered multiconductor transmission lines in strongly inhomogeneous media. We mainly focus on designing of five-transmission lines embedded in four-layered dielectric media. We computed the capacitance matrices for this configuration. Also, we determine the quasi-TEM spectral for the potential distribution of the multiconductor transmission lines in multilayer dielectric media.
