Tunable plasmonic enhancement of light scattering and absorption in graphene-coated subwavelength wires
The electromagnetic response of subwavelength wires coated with a graphene monolayer illuminated by a linearly polarized plane waves is investigated. The results show that the scattering and extinction cross-sections of the coated wire can be dramatically enhanced when the incident radiation resonan...
