Performing Two-Dimensional Differentiation with Gap Plasmon-based Metasurface

Not Accessible

Your library or personal account may give you access

Abstract

We numerically demonstrate spatial differentiation using circular gap-plasmon resonators arranged in a square lattice. The metasurface enables ultrafast analog computing and two-dimensional edge detection for image processing.
