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 &\#x3F5; and permeability &\#x3BC;. In this Letter, we use a scheme for transforming surface currents to highlight that the surface conductivity transforms in a way different from &\#x3F5; and &\#x3BC;. We use this surface conductivity transformation to demonstrate an example problem of reducing the scattering of the plasmon mode from sharp protrusions in graphene.
