Effective Design of Graphene Patch Arrays for Adjustable Plane-Wave Scattering

In this document, the scattering properties of graphene patches are investigated to design arrays that are able to control effectively plane wave propagation. Initially, single patches are examined in terms of their radar cross-section and surface wave generation. Moreover, an array of four identical elements is designed and thoroughly investigated indicating that electrostatic bias field has not a significant effect. However, the application of non-uniform biasing on the same setup reveals the fine adjustment of the scattered wave's main lobe direction.
