An experimental graphene optical system uses red, green and blue light challenges, transformer-assisted image analysis and binary codes to create programmable hardware-based authentication responses.

In this paper, we examine the transmission probability through a symmetric double bilayer-graphene junction modulated by Fano-type interference. At oblique incidence, two trajectories generated by ...

A broad range of optical devices use nanostructured layers and surfaces to manipulate beams of light through diffraction and interference. Example devices include diffraction gratings, metasurfaces, ...
