This paper reviews the basic concept of the frequency-domain TLM metho
d. Various formulations for the frequency-domain nodes are derived fro
m the symmetrical condensed node. It will be shown that different node
representations lead to different dispersion errors which in turn wil
l have a direct effect on the computational accuracy. The flexibility
and potential of the FDTLM method will be discussed and a wide range o
f applications will illustrate the usefullness of this approach.
