Georgia Tech researchers propose terabit level graphene antenna

( —Researchers at Georgia Institute of Technology, led by lab director Ian Akyildiz, are proposing that a graphene antenna could be built that would be capable of transferring data at the 10 to 100 terabit level. In a paper to be published in IEEE‘s Journal of Selected Areas in Communication, the team will outline how a nano-sized antenna made of graphene could be constructed that would take advantage of the materials’ superfast electron transfer properties.

Graphene has been making headlines over the past few years as researchers discover new ways to make use of its unique properties—its one layer of carbon atoms arranged in a honeycomb structure offer almost no resistance to electrons which allows for much faster movement of electricity than metal or silicon. In this new research, the team believes it would be possible to take advantage of electron oscillations (plasmonic waves) that occur on its surface, at the terahertz range, to send and receive data.

The antenna the researchers envision would be made of strips of graphene approximately 10 to 100 nanometers wide and approximately one micrometer in length. Such an antenna, the researchers suggest, could transmit 10 terabits of data per second between two devices situated approximately one meter apart. Moving the two devices closer, to just centimeters apart, could bump the rate to 100 terabits of data per second.

That would be equivalent to moving all of the data on a full large capacity hard drive to another in about the time it takes to swallow a mouthful of coffee.
