✦ Synopsis


An equivalent circuit for a symmetrical condensed TLM node is presented. The basic circuit has twelve ports and consists of 24 1: 1 ideal transformers. Three additional conductances model the conductivity of the medium. The circuit is extended with additional ideal transformers giving six ports for short-circuit and open-circuit stubs which model the permittivity and permeability of the inhomogeneous medium. The scattering matrix of the 18-port network is determined symbolically by solving a set of linear circuit equations. The matrix agrees with previously published results for a symmetrical condensed TLM node, obtained from Maxwell's equations.

Electric circuit models are constructed for general symmetric systems of linear algebraic equations. The modelling procedure is based on the node-voltage analysis of linear circuits under steady-state conditions. These electric circuit models can, in principle, be physically realized and used for th
