Abstract

Two-dimensional optical materials, such as graphene, can be characterized by surface conductivity. So far, the transformation optics schemes have focused on three-dimensional properties such as permittivity $ϵ$ and permeability $\mu$. In this Letter, we use a scheme for transforming surface currents to highlight that the surface conductivity transforms in a way different from $ϵ$ and $\mu$. We use this surface conductivity transformation to demonstrate an example problem of reducing the scattering of the plasmon mode from sharp protrusions in graphene.
