Effective properties of membrane photonic crystals - art. no. 70410R
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.
