Conférence invité: META 2023 (Paris, FR, 2023-07-18) Ref HAL: hal-04171737_v1 Exporter : BibTex | endNote Résumé: We present a simplification of the Fourier Modal Method (FMM) for crossed gratings with subwavelength heights. We show that in this case it is possible to compute the scattering matrix of the structure without solving the eigenvalue problem which is the most expensive computational part of the FMM algorithm. This approach is very efficient and thus suitable for periodic metasurfaces. |
