Résumé
In its conventional form, the Transmission Line Modeling method is not capable of accounting for media whose constitutive parameters are exotic. Permittivity and permeability less than unity can be reached by using a mesh that is the numerical counterpart of a dispersive left-handed transmission line network. In this communication, the dispersion thus introduced in a two-dimensional node is shown to follow a Drude profile. This property is verified on an example involving an infinite cylinder made up of metamaterial.
