چکیده انگلیسی
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 second identity. Enhancement of these efficiencies is observed when the emission frequency coincides with one of the plasmonic resonance frequencies of the wire. The relevance of the dipole emitter position and the dipole moment orientation are evaluated. We present calculations of the near-field distribution for different frequencies which reveal the multipolar order of the plasmonic resonances.
