The modelling of general constitutive relationships in SCN (Symmetrical Condensed Node) TLM is presented. The technqiue consists of decoupling the scattering matrix from the medium by using equivalent node sources with state-variable formulation of the constitutive relationships. The procedure requires few modifications to TLM. Numerical examples are presented.
