Tunable Graphene Reflective Cells for THz Reflectarrays and Generalized Law of Reflection
Eduardo Carrasco, Michele Tamagnone, Julien Perruisseau-Carrier
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 refle…
Manipulation of Giant Faraday Rotation in Graphene Metasurfaces
Arya Fallahi, Julien Perruisseau-Carrier
Faraday rotation is a fundamental magneto-optical phenomenon used in various optical control and magnetic field sensing techniques. Recently, it was shown that a giant Faraday rota…
Design of Tunable Biperiodic Graphene Metasurfaces
Arya Fallahi, Julien Perruisseau-Carrier
Periodic structures with subwavelength features are instrumental in the versatile and effective control of electromagnetic waves from radio frequencies up to optics. In this paper,…
Comment on 'Encoding many channels on the same frequency through radio vorticity: first experimental test'
Michele Tamagnone, Christophe Craeye, Julien Perruisseau-Carrier
We show that the public experiment held in Venice by F. Tamburini et al and reported in (2012 New J. Phys. 14 033001) can be regarded as a particular implementation of Multiple-Inp…
Graphene for Antenna Applications: Opportunities and Challenges from Microwaves to THz
Julien Perruisseau-Carrier
The use of graphene for antennas and other electromagnetic passives could bring significant benefit such as extreme miniaturization, monolithic integration with graphene RF nanoele…
Reconfigurable THz Plasmonic Antenna Concept Using a Graphene Stack
Michele Tamagnone, Juan Sebastian Gomez Diaz, Juan Ramon Mosig +1
The concept and analysis of a Terahertz (THz) frequency-reconfigurable antenna using graphene are presented. The antenna exploits dipole-like plasmonic resonances that can be frequ…
