The modeling and analysis of Multiconductor systems for radio work is of the utmost importance. In this work we will present Mathematica ® code for Modeling Multiconductor Transmission Lines. The Code is Written by Dr. Sasan Ardalan. The work is based on Research at NC State by Professor Sasan Ardalan, Mike Riddle and John Suh ( Both Masters Electrical Engineering) while at NC State University (1988).

Where possible the Mathematica® Code is GPL Open Source. Also see the Open Source Transmission Line Network Modeling Program (C Code and TCL).

For the derivation of the Voltage and Current Transfer Functions for Multiconductor Transmission Lines see this report in PDF. Also published in the IEEE International Conference on Circuits and Systems, 1989. This is a key document. The Mathematica® code is based on the formulas derived in this paper.

The paper also has simulation results that match very closely with experimental results presented by the late Professor Clayton Paul. Professor Clayton Paul did fundamental work in Multiconductor Transmission Lines and the Derivation of Per Unit Parameters. See his book on the Analysis of Multconductor Transmission Lines here.

By providing the Code in Mathematica® you can dig deep into the formulas as well as per unit parameters, propagation matrices and impedances as they are calculated. You can further investigate the matrices involved and try out new algorithms. This is a huge advantage over FORTRAN and C Code for Research and Development purposes. Hence the effort by RadioCalc.Com.
