Abstract :
The general dispersion equation, derived for the 3-D transmission line matrix (TLM) condensed node mesh, is presented and compared to dispersion of the finite-difference time-domain and the expanded node TLM schemes. Spurious mode propagation, as predicted by the dispersion equation for the condensed node, is also addressed. Analysis of dispersive effects is essential to assessing abnormalities in time-domain simulations.<>
