Towards Random Metasurface based Devices
Matthieu Dupré, Liyi Hsu, Boubacar Kanté
Metasurfaces are generally designed by placing scatterers in a periodic grid. We propose and discuss design rules for efficient random and functional metasurfaces with anisotropic…

From parabolic-trough to metasurface-concentrator
LiYi Hsu, Matthieu Dupré, Abdoulaye Ndao +1
Metasurfaces are promising tools towards novel designs for flat optics applications. As such their quality and tolerance to fabrication imperfections need to be evaluated with spec…
