An important aspect in the application of transmission-line modelling
(TLM) to microwave circuit and electromagnetic compatibility (EMC) sim
ulation studies is the accurate modelling of wires and wire-like struc
tures. This paper outlines the cause of errors arising from simplified
descriptions often used when modelling wires by integrated solution m
ethods in TLM. It proposes a simple solution which is validated agains
t experimental results for a number of test configurations.
