Graphene metasurface makes the thinnest possible cloak in the terahertz spectrum

We propose metasurface cloak designs composed of subwavelength graphene nanopatches to realize wideband-tunable scattering cancellation in the terahertz (THz) spectrum. By adjusting the parameters and Fermi energy of graphene nanopatches, an inductive or capacitive surface reactance can be tailored at will, thereby enabling the scattering suppression of different dielectric and conductive micro-scale objects.
