From: Ultrabroadband, More than One Order Absorption Enhancement in Graphene with Plasmonic Light Trapping
Light absorption in graphene for different separations between the graphene layer and metallic crosses.
The separation varies from 0 to 20 nm. The separation layer is assumed to be lossless with a refractive index of 1.5. The flat dashed line shows the absorption in a free standing graphene without enhancement.
