enhancement in the graphene due to the plasmonic oscilla-tions [3, 6]. Optical excitation of surface plasmons originates from optically-induced oscillations of free charges (conduction electrons) bound at the metal–dielectric interface. One tech-nique to couple light to plasmonic oscillations is to diffract light by plasmonic nanostructures [22].
