A Modified Enhanced Transmission Line Theory Applied to Multiconductor Transmission Lines

Abstract

International audienceIn 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. © 2016 IEEE

An Embedded Double Reference Transmission Line Theory Applied to Cable Harnesses

“…Recently, the authors have also developed a new TL model that keeps the simplicity of the classical TLT equations and leads to very satisfactory results in high frequency regions and even at resonances. This model (called the modified enhanced transmission line theory, METLT) is valid in the case of a single wire as well as for a multi-conductor transmission line [8]- [10]. Its main particularity is that its p.u.l.…”

“…Superscript 'SR' is used in the following equations to indicate that all quantities such as voltages, currents, impedances, admittances are calculated with the ground plane as a single reference. Transmission line theory coupled equations are given by [10]:…”

Applying the Retarded Solutions of Electromagnetic Fields to Transmission Line RLGC Modeling

“…We observe the electromagnetic fields on the surface of the PEC reference plane, for ℎ = 10 and ℎ = 100 , respectively. We plot the magnitude of the fields in color where positive peak is in red and negative peak is in blue.…”

“…The medium is again assumed to be uniform and lossless with ε = 4 and μ = . Here, the height above the reference plane, h, is chosen to be 100 mils which is significant enough to invalidate the Classical Model (generally assumed to be one tenth of a wave length [10] ).…”

“…In Chabane et al, 4 the per-unit-length parameters are frequency dependent and include, even for lossless wires, high frequency (HF) resistance and conductance matrices.…”
