Abstract :
We introduce a new TLM node approach for the analysis of wave-propagation in electro-optical devices. The present model accounts for both permittivity and permeability tensors of the material. The node scattering matrix is derived by using centered differences and averages. The novel aspect is that stub-loaded reactances are derived by consideration of the refractive-index ellipsoid.
