Opt Express 17:22603-8. 2009..The validity of our approach is confirmed by finite edge-elements computations for a non-convex cloak of varying thickness...
- All-purpose finite element formulation for arbitrarily shaped crossed-gratings embedded in a multilayered stackGuillaume Demesy
Institut Fresnel, Universite Aix Marseille, Ecole Centrale Marseille, Campus de Saint Jérôme, 13013 Marseille, France
J Opt Soc Am A Opt Image Sci Vis 27:878-89. 2010..Finally, computation time and convergence as a function of the mesh refinement are discussed. As far as integrated energy values are concerned, the presented method shows a remarkable convergence even for coarse meshes...
