Single and two dimensional carbon materials represent a major development in advanced materials of the past two decades, with potential major disruptive applications across ICT, high frequency electronics. The microwave interactions of these materials has only much more recently been investigated. In this paper we present details of a very sensitive non-invasive method to characterize the electrical properties of graphene at the large scale, also the investigation of carbon nanotubes as high frequency interconnects and graphene nano-electromechanical resonators driven and detected by a microwave resonator near-field technique. We speculate on future microwave and reduced dimension carbon applications.
