A new and efficient technique is presented for modelling and simulation of interconnect networks which include multiconductor microstrip transmission lines (MMTL) with inhomogeneous cylindrical substrates. The potential and field distributions in the cross section of the MMTL are calculated by solving a set of series equations using Galerkin's method. The charge distribution on the conductors, maxwellian capacitance matrix per unit length, and the modal characteristic impedances of the MMTL are determined. Results obtained have been compared for various types of microstrip lines with those obtained in the literature; good agreement has been found.
