A MATLAB-based transmission-line virtual tool: finite-difference time-domain reflectometer

Abstract

This article introduces a simple virtual tool, TDRMeter, for the investigation and visualization of time-domain pulsed voltage/current, traveling along a terminated finite-length transmission line, without and with faults somewhere between the source and the load. The package can be used as an educational tool in various undergraduate lectures to aid in teaching electromagnetics as well as transmission lines.
