Microwave propagation along graphene at microscopic and macroscopic scales

In this paper, the properties of graphene in both microscopic and macroscopic scale are studied. Different equivalent circuit models are implemented to characterize the signal integrity of graphene-based interconnect and to extract the surface conductivity of graphene. On the one hand, input/output voltage of different interconnect structures is explored and eye diagram is utilized for further study of signal integrity. On the other hand, a novel contact-free characterization method is proposed to extract the surface conductivity of graphene which is grown by chemical vapor deposition.
