Transmission line matrix (TLM) methods are powerful numerical procedures for modeling electromagnetic fields in the time domain. The theoretical foundations of various TLM methods are well described in the literature, but to develop general purpose simulation software based on the procedures is still a challenging task. The computational electromagnetics industry is by and large responsible for implementing the procedures in commercially available software. However, many open-source and free software packages have been written by researchers; some of these packages also come with a graphical user interface.The finite difference time domain (FDTD) technique and TLM methods are two similar time-domain numerical procedures for modelling electromagnetic fields. Instead of updating the electric and magnetic field quantities as is done in the FDTD procedure, TLM methods update the voltage quantities using a voltage scattering procedure. Electric and magnetic field quantities are not needed to carry out the scattering process; the field quantities of course can be obtained from the voltage quantities if needed.
