Among these, a particularly promising emerging field is graphene-enabled wireless communications. Wireless communications among nanosystems cannot be achieved by simply reducing the size of classical metallic antennas, since that would impose the use of very high resonant frequencies in the optical range. Due to the expectedly very limited power of nanosystems, the low mobility of electrons in metals when nanometer scale structures are considered, and the challenges in implementing a nanotransceiver able to operate at this extremely high frequency, the feasibility of wireless communications at the nanoscale would be compromised if this approach were followed. Moreover, scaling down metallic antennas to a size of just a few micrometers would make them non-resonant and hence dramatically reduce their antenna efficiency.
