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…
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…
Nonlocal Electromagnetic Response of Graphene Nanostructures
Arya Fallahi, Tony Low, Michele Tamagnone +1
Nonlocal electromagnetic effects of graphene arise from its naturally dispersive dielectric response. We present semi-analytical solutions of nonlocal Maxwell's equations for graph…
MEMS-reconfigurable metamaterials and antenna applications
Tomislav Debogovic, Julien Perruisseau-Carrier
This paper reviews some of our contributions to reconfigurable metamaterials, where dynamic control is enabled by micro-electro-mechanical systems (MEMS) technology. First, we show…
Self-biased Reconfigurable Graphene Stacks for Terahertz Plasmonics
J. S. Gomez-Diaz, C. Moldovan, S. Capdevilla +5
The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at THz and mid-IR frequencies. However, the requirement of a…
Predicting input impedance and efficiency of graphene reconfigurable dipoles using a simple circuit model
Michele Tamagnone, Julien Perruisseau-Carrier
An analytical circuit model able to predict the input impedance of reconfigurable graphene plasmonic dipoles is presented. A suitable definition of plasmonic characteristic impedan…
