Tunable terahertz cloaking and lasing by the optically pumped graphene wrapped on a dielectric cylinder

The scattering properties of a dielectric cylinder wrapped by a monolayer of graphene under an external optical pump are investigated. The THz cloaking is realized due to the strong suppression of scattering at certain range of frequencies. While at some other frequencies, the scattering can be dram...
