Transmission-Line Matrix Method
The Transmission-Line Matrix (TLM) method is a direct discretization of Maxwell equations using an equivalent transmission line network. Introduced by Johns and Beurle in 1971, TLM models electromagnetic fields as voltage and current waves propagating on coupled transmission lines. The method is intuitive, numerically stable, and efficient for both transient and frequency-domain electromagnetic problems. TLM remains competitive with FDTD and FIT for many RF and microwave applications.
