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 ...

Reconfigurable graphene metasurfaces: determining and approaching theoretical upper bounds

Julien Perruisseau-Carrier, Michele Tamagnone

2014

Fundamental 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 ...

Predicting 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 ...

Graphene 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 ...

High-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 ...

Tunable 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 ...

Comment 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 ...

Comment on “Encoding many channels on the same frequency through radio vorticity: first experimental test”

Julien Perruisseau-Carrier, Michele Tamagnone

We show that the public experiment held in Venice by Tamburini et al and reported in 2012 New J. Phys. 14 033001 can be regarded as a particular implementation of multiple-input-multiple-output (MIMO) communications and, therefore, has no advantages over e ...
