Quantification of the transmission properties of metasurfaces illuminated by finite-size beams
Mohamed Boutria, Abdoulaye Ndao, Fadi I. Baida
The aim of this letter is to {present analytical method to} quantitatively address the influence of a focusing illumination on the transmission /reflection properties of a {metasur…
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…
Plasmonless polarization-selective metallic Semi-coaxial Aperture Arrays in the visible range
Abdoulaye Ndao, Roland Salut, Fadi I. Baida
In this letter, we perform numerical and experimental studies of the optical response of an original configuration based on enhanced transmission through guided mode based metamate…
Brillouin spectroscopy of optical microwires
Adrien Godet, Abdoulaye Ndao, Thibaut Sylvestre +5
We describe an easy-to-implement technique that allows for a complete experimental characterization of sub-wavelength diameter tapered optical fibers. Our method is based on a dire…
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…
