Advancing wavefront shaping with resonant metasurface
Résumé
In metasurface design, the use of look-up tables based on a local periodicity approximation have been tradi-
tionally employed, but can result in sub-optimal designs due to lack of consideration of near-field coupling
effects, which are particularly important for resonant systems. This paper explores the benefits of taking into
account near-field coupling while optimizing non-local resonant metasurfaces to enhance their performance for
wavefront shaping, including the state-of-the-art Huygens’s metasurface.
