Abstract

A stub leakage resistor at the nodes of an otherwise lossless TLM chain (i.e. without series resistors) introduces losses, although the corresponding absorption term in the Telegraphers' equation vanishes due to the absence of series resistors. This contradiction is outlined, an explanation is proposed and the practical implications are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
