The FD-TD formulation of the 3D TLM symmetrical condensed node and its applications

摘要

In this paper, the finite-difference time-domain (FD-TD) formulation of the 3D transmission-line-matrix (TLM) symmetrical condensed node is presented. It allows a direct use of field quantities and therefore the applications of modelling tools and techniques developed for the conventional TD-TD method. Numerical results are given for modelling general electromagnetic media including anisotropic, dispersive and nonlinear media.
