TL;DR: X60 is introduced, the first SDR-based testbed for 60 GHz WLANs, featuring fully programmable MAC/PHY/Network layers, multi-Gbps rates, and a user-configurable 12-element phased antenna array, and it is found that a one-to-one MCS to SNR mapping is hard to obtain in typical indoor environments.
Journal ArticleDOI
Design and Operation of a Graphene-Based Plasmonic Nano-Antenna Array for Communication in the Terahertz Band
TL;DR: A novel THz plasmonic array architecture which leverages the properties of graphene to greatly simplify its design and operation is presented and the advantages of this array architecture over conventional array architectures are discussed.
Proceedings ArticleDOI
Design of graphene-based plasmonic nano-antenna arrays in the presence of mutual coupling
TL;DR: In this article, the performance of plasmonic nano-antenna arrays is analyzed while taking into account mutual coupling effects, and the array factor and total gain for nano-array arrays are derived.
Journal ArticleDOI
Lithographically Defined Plasmonic Graphene Antennas for Terahertz-Band Communication
TL;DR: In this paper, it was shown that the width of the surrounding cut is comparable to the plasmonic wavelength, which opens the door to practical and more advanced antenna designs.
Proceedings ArticleDOI
Graphene-based plasmonic phase modulator for Terahertz-band communication
TL;DR: In this paper, a graphene-based plasmonic phase modulator for Terahertz band (0.1-10 THz) communication is proposed, modeled and analyzed.
