Transmission line matrix (TLM) algorithms for lossy electrical network prov
ide a solution for the telegrapher's equation. In spite of the fact that th
ese constitute a lossy wave equation analogue, they have been successfully
used to model thermal problems. This paper discusses the relationship betwe
en the hyperbolic and parabolic formulations and shows how TLM can be succe
ssfully applied in both regimes. (C) 1999 Elsevier Science Ltd. All rights
