Graphene Antennas Could Power Nanoscale Machines

Posted on: 12/13/2013
Researchers at the Georgia Institute of Technology (Georgia Tech) are exploring the use of graphene to create tiny antennas powerful enough to operate nanoscale devices. The research could have implications for medical, industry, environmental protection, and defense uses.

Traditional metallic antennas have limited capability for communication. Graphene, by contrast, has qualities that enable it to generate an electronic surface wave that would allow antennas one micron long and 10 to 100 nanometers wide to do the work of much larger antennas.

Graphene nano-antennas have yet to be demonstrated, but the researchers say their modeling and simulations show that nano-networks using the new approach are feasible.
