A New Method of Determining the Transmission Line Parameters of an Untransposed Line using Synchrophasor Measurements
Transmission line parameters play a significant role in a variety of power system applications. The accuracy of these parameters is of paramount importance. Traditional methods of determining transmission line parameters must take a large number of factors into consideration. It is difficult and in …

Transient analysis of lossy multiconductor transmission lines in nonlinear circuits
Using the frequency-dependent transmission line parameters, two time-domain models are developed for lossy multiconductor transmissions lines. It is shown that the endpoints of a lossy multiconductor line can be represented at each time step by discretized Thevenin or Norton equivalent circuits. …

Numerical Modeling of Multi-Conductor Interconnects for High Speed Integrated Circuits
… an alternative methodology to the development of transmission line models for multi-conductor interconnects in high speed integrated circuits. The methodology starts with the assumption that per unit length (p.u.l.) transmission line parameters — i.e. p.u.l. resistance R, inductance L, capacitance …

Superconducting coplanar delay lines
Two 25 ns wideband HTS delay lines with a novel double-spiral meander line (DSML) structure are designed, fabricated and measured. One is based on the conventional coplanar waveguide (CPW), and the other based on a conductor-backed coplanar waveguide (CBCPW). Systematic design work is presented in …
