Graphennas – a seemingly far-fetched idea of tiny antennas composed of graphene – are one step closer to revolutionizing nanotechnology thanks to recent tests published in IEEE Transactions on Communications. Or at least, they’re one step closer to reality. While the hypothetical concept of graphennas has been introduced in...

In the world of wireless communications, the concept of the buffer-aided relay usually generates interest because some believe it could improve connectivity and eliminate the familiar “sorry-can-you-hear-me-now?” moments resulting from weak signals. But could it also hold the key to more-secure communications? In a paper recently published in IEEE Transactions ...
