Gate-controlled mid-infrared light bending with aperiodic graphene nanoribbons array
Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone
Graphene plasmonic nanostructures enable subwavelength confinement of electromagnetic energy from the mid-infrared down to the terahertz frequencies. By exploiting the spectrally varying light scattering phase at the vicinity of the resonant frequency of t ...
Institute of Physics2015The Orbital Angular Momentum (OAM) Multiplexing Controversy: OAM as a subset of MIMO
Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone, Joana Rita Alves dos Santos Silva, Santiago Capdevila Cascante
Recently the orbital angular momentum (OAM) multiplexing scheme has been proposed to increase supposedly without limit the channel capacity between a transmitter and a receiver nodes communicating in line of sight. A controversy arose about the far-field e ...
2015Steep-slope Metal-Insulator-Transition VO2 Switches with Temperature-Stable High ION
Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Michele Tamagnone, Wolfgang Amadeus Vitale, Antonio Paone
This work reports a detailed experimental investigation of the slope of the current switching between OFF and ON states exploiting the metal-insulator-transition in vanadium dioxide devices. The reported devices are CMOS compatible 2-terminal switches. We ...
Institute of Electrical and Electronics Engineers2015Fundamental limits and near-optimal design of graphene modulators and non-reciprocal devices
Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone
The potential of graphene for photonic applications was evidenced by recent demonstrations of modulators, polarization rotators and isolators. These promising yet preliminary results raise crucial questions: what is the optimal performance achievable by mo ...
Nature Publishing Group2014Predicting Input Impedance and Efficiency of Graphene Reconfigurable Dipoles Using a Simple Circuit Model
Julien Perruisseau-Carrier, Michele Tamagnone
An analytical circuit model able to predict the input impedance of reconfigurable graphene plasmonic dipoles is presented. A suitable definition of plasmonic characteristic impedance, employing natural currents, is used to for consistent modeling of the an ...
Institute of Electrical and Electronics Engineers2014Graphene Antennas: Can Integration and Reconfigurability Compensate for the Loss?
Julien Perruisseau-Carrier, Michele Tamagnone
In this opening presentation we will first recall the main characteristics of graphene conductivity and electromagnetic wave propagation on graphene-based structures. Based on these observations and different graphene antenna simulations from microwave to ...
Ieee2013Tunable graphene reflective cells for THz reflectarrays and generalized law of reflection
Julien Perruisseau-Carrier, Michele Tamagnone, Francisco Eduardo Carrasco Yepez
A tunable graphene-based reflective cell operating at THz is proposed for use in reconfigurable-beam reflectarrays, or similarly to implement the so-called generalized law of reflection. The change in the complex conductivity of graphene when biased by an ...
American Institute of Physics2013High-impedance frequency-agile THz dipole antennas using graphene
Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone
The concept and analysis of a THz frequency-reconfigurable antennas using graphene are presented. The antennas exploit dipole-like plasmonic resonances that can be frequency-tuned on large range via the electric field effect in a graphene stack. In additio ...
Ieee2013Tunable graphene-based reflectarray element for reconfigurable beams
Julien Perruisseau-Carrier, Michele Tamagnone, Francisco Eduardo Carrasco Yepez
Tunable reflective elements based on graphene patches are proposed for reconfigurable-beam reflectarray antennas. The complex conductivity of graphene can be dynamically varied when an electric field is applied, allowing to control the phase of the reflect ...
Ieee2013Comment on “Reply to Comment on ‘Encoding many channels on the same frequency through radio vorticity: first experimental test’”
Julien Perruisseau-Carrier, Michele Tamagnone
We show that the reply by Tamburini et al (2012 New J. Phys. 14 118002) to our previous comment (2012 New J. Phys. 14 118001) on the experiment reported in Tamburini et al (2012 New J. Phys. 14 033001) does not actually invalidate any of the issues raised ...
