Abstract :
The paper describes the development of a class of adaptable symmetrical condensed (ASCN) transmission-line modeling (TLM) nodes. The parameters and numerical properties of the ASCN are expressed in terms of arbitrary weighting functions which can be selected in a manner that minimizes dispersion and improves accuracy. It is shown that this approach is effective and can be used to optimize nodal properties according to problem requirements
