Computation of Capacitance of Shielded and Coupled Transmission Lines

In this paper, we present the modeling of shielded three vertically coupled striplines and shielded four coupled microstrip lines embedded in a dielectric material media using finite element method (FEM). We specifically determine the capacitance per unit length of shielded three vertically coupled striplines and shielded four coupled microstrip lines embedded in a dielectric material. We compare our results with those obtained by method of lines (MoL) and found them to be in good agreement.
