Graphene Reflectarray Metasurface for Terahertz Beam Steering and Phase Modulation
Michele Tamagnone, Santiago Capdevila, Antonio Lombardo +6
We report a THz reflectarray metasurface which uses graphene as active element to achieve beam steering, shaping and broadband phase modulation. This is based on the creation of a…
Magnetoplasmonic Enhancement of Faraday Rotation in Patterned Graphene Metasurfaces
Michele Tamagnone, Tetiana M. Slipchenko, Clara Moldovan +10
Faraday rotation is a fundamental property present in all non-reciprocal optical elements. In the THz range, graphene displays strong Faraday rotation; unfortunately, it is limited…
Spatial Multiplexing of QPSK Signals with a Single Radio: Antenna Design and Over-the-Air Experiments
Mohsen Yousefbeiki, Andrew C. M. Austin, Juan R. Mosig +2
The paper describes the implementation and performance analysis of the first fully-operational beam-space MIMO antenna for the spatial multiplexing of two QPSK streams. The antenna…
Near-Field Perturbation Effect on Constellation Error in Beam-Space MIMO
Mohsen Yousefbeiki, Juan R. Mosig, Andreas P. Burg
Beam-space MIMO has recently been proposed as a promising solution to enable transmitting multiple data streams using a single RF chain and a single pattern-reconfigurable antenna.…
Gate-controlled mid-infrared light bending with aperiodic graphene nanoribbons array
Eduardo Carrasco, Michele Tamagnone, Juan R. Mosig +2
Graphene plasmonic nanostructures enable subwavelength confinement of electromagnetic energy from the mid-infrared down to the terahertz frequencies. By exploiting the spectrally v…
Fundamental limits and near-optimal design of graphene modulators and non-reciprocal devices
Michele Tamagnone, Arya Fallahi, Juan R. Mosig +1
The potential of graphene for use in photonic applications was evidenced by recent demonstrations of modulators, polarisation rotators, and isolators. These promising yet prelimina…
