Spontaneous emission in plasmonic graphene subwavelength wires of arbitrary sections

We present a theoretical study of the spontaneous emission of a line dipole source embedded in a graphene–coated subwavelength wire of arbitrary shape. The modification of the emission and the radiation efficiencies are calculated by means of a rigorous electromagnetic method based on Green's s...
