Résumé: Wave propagation in thin nanostructured films in the low frequency regime is studied. By means of a two-scale analysis, it is shown that the medium can be homogenized, i.e. described by effective electromagnetic parameters. The effective permeability and permittivity are obtained by solving a set of partial differential equations. A numerical aproach based on the Fourier Modal Method is proposed in order to solve these equations.

Résumé: The direction of propagation followed by a monochromatic beam in a periodic structure is generally deduced from the isofrequency diagram, which is related to the group velocity. However, the group velocity is the derivative of ω with respect to the wavenumber, while the behavior of the beam should depend on ω only. In the subwavelength regime, a method for choosing the relevant branch of the isofrequency diagram and relying on the behavior of the system at ω only is described.
