THE FREQUENCY-DOMAIN TLM METHOD—THEORY AND APPLICATIONS

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