In this paper, an accurate modeling procedure for GaAs MESFET as active coupled transmission line is presented. This model can consider the effect of wave propagation along the device electrodes. In this modeling technique the active multiconductor transmission line (AMTL) equations are obtained, which satisfy the TEM wave propagation along the GaAs MESFET electrodes. This modeling procedure is...

This paper introduces a novel algorithm for delay extraction-based passive macromodeling of multiconductor transmission line type interconnects characterized by multiport (Y, Z, S, or H) tabulated parameters. The algorithm determines a unique logarithm of the H parameters, which is then approximated using a low-order rational function. Subsequently, the DEPACT (delay extractionbased passive com...

Transmission line theory and a genetic algorithm are used herein for extracting per-unitlength parameters of microstrip or striplines with dispersive dielectric substrates. S-parameters of the line section are measured and used as an objective function for global optimization. The discrepancy between the modeled and measured results is minimized over all the frequency range of interest. Wave eq...

A complete methodology is employed to determine the transmission characteristics of low-voltage/broadband over power lines (LV/BPL) channels associated with underground power distribution networks, in the light of the multiconductor transmission line (MTL) theory. The established bottom-up approach, already used to treat overhead and underground MV/BPL transmission, is extended to analyze BPL t...

Starting with Maxwell's equations, the transmission line equations are derived for a system consisting of an arbitrary number of conductors. The derivation is rigorous for long lossless conductors embedded in a uniform perfect dielectric. The presentation is essentially tutorial, most of the results being well known, at least for twoand three-conductor systems. The novelty lies in the point of ...

Boards F. Sabath , H. Garbe University of Paderborn C-LAB, Paderborn, Germany University of Hannover, Hannover, Germany Abstract This paper deals with the coupling between traces on Printed Circuit Boards (PCB). Particularly a method is presented which allows to estimate the deviation of the current distribution on an active trace due to the omission of recoupling by an adjacent trace. An e ect...

this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...
