I. Introduction
In recent years, carbon and its derivative materials have proven to be an emerging alternative for conventional materials due to their excellent electronic, mechanical and thermal characteristics. These unique set of characteristics grants carbon based materials a wide range of applications [1]–[2]. Graphene is par excellence the most noticeable of carbon materials for components and devices at frequencies ranging from DC up to terahertz (e.g. [3]–[5]) and beyond.
