Abstract
In this paper, a multiconductor modified enhanced transmission line theory is presented. The constitutive equations of this theory are directly derived from Maxwell's equations without the restriction to the transverse electromagnetic mode, while conserving the mathematical formalism of the classical transmission line theory (TLT). However, the per-unit-length (p.u.l.) parameters become complex and frequency dependent but still have an RLCG form. Besides, these new parameters are expressed as a combination of the classical ones and a high-frequency correction. These equations can be easily solved by the existing classical TLT solvers. The results obtained by this theory are in a much better agreement than the classical TLT with those predicted by a full-wave solver or measurements.
