"Graphene for EM waves and reflectarrays"

The use of graphene for antennas and other electromagnetic (EM) passive devices could bring significant benefit such as efficient dynamic tuning, miniaturization, monolithic integration with graphene RF nanoelectronics, and even transparency and mechanical flexibility. I will briefly review the main properties of graphene for such applications and its modelling in a "Maxwellian" framework. I will then discuss a number of possible applications, assessing the potential benefits of graphene but also its limitations and remaining issues towards real-life implementations. Examples of devices proposed are graphene resonant and leaky-wave antennas, isotropic and anisotropic meta-surfaces for a variety of applications. I will also discuss graphene-based reflectarrays, after a brief introduction to the reflectarray concept and our past work using non-graphene technologies.
