GRANET: Graphene-enabled Nanonetworks in the Terahertz Band

Overview

Nanotechnology is providing a set of tools to the engineering community to design novel devices just a few hundred nanometers in size, which are able to perform only very simple tasks. Nanonetworks, i.e., networks of nano-devices, will enable more advanced applications of nanotechnology in the defense, military, biomedical and environmental fields. To date, however, it is not clear how nano-devices will communicate. Scaling a metallic antenna down to a few hundred nanometers would impose the use of very high operating frequencies, thus, drastically limiting the communication range of nano-devices. Alternatively, graphene can be used to develop nano-antennas able to radiate at much lower frequencies. Interestingly, this frequency band matches the initial predictions for the operation frequency of graphene-based radio-frequency (RF) components in future nano-transceiver architectures.

The fundamental research objectives of this project are to prove the feasibility of graphene-enabled electromagnetic communication among nano-devices and to establish the scientific foundations of electromagnetic nanonetworks in the Terahertz band. The specific outcomes of the project are: i) experimental prototypes of graphene-based nano-antennas, ii) experimental prototypes of high-speed nano-transceivers for Terahertz communications, iii) a Terahertz channel model for short-range communication in nanonetworks, and iv) new information theoretic fundamentals of communication among nano-devices. The final proof-of-concept of the project will be the establishment of a one-to-one link between two nano-transceiver & nano-antenna prototypes.
