Performing Spatial Differentiation and Edge Detection with Dielectric metasurfaces

Not Accessible

Your library or personal account may give you access

Abstract

Spatial differentiation and edge detection have been proposed to realize with a dielectric metasurface by engineering the spatial dispersion of electric dipole resonance. The results show excellent performances for 2D images.
