We explore the unusual electromagnetic response of magnetically-biased densely-packed graphene ribbons. Applying an effective medium approach, we show how the presence of a magnetostatic bias induces resonances on all components of the effective conductivity tensor, significantly enriching the features of the supported surface plasmons polaritons (SPPs). Specifically, we demonstrate magnetically-induced...
We explore the electromagnetic response of ultrathin metasurfaces realized by densely-packed arrays of graphene strips. We analyze various topologies of propagation bands supported by this structure, ranging from the canalization regime found at a few terahertz (THz), hyperbolic responses present at a few dozens of THz, and anisotropic elliptic TE and TM regimes that arise at mid-infrared frequencies...
The properties of surface plasmons supported by infinitesimally thin hyperbolic metasurfaces are investigated in detail. Hyperbolic metasurfaces are rigorously modelled using uniaxial conductivity tensors, thus taking into account their combined dielectric/metallic nature. The dispersion relation of the supported modes is analytically derived and asymptotically simplified to closely follow the branches...
The pioneering theoretical and experimental research in terahertz graphene plasmonics developed by Prof. Julien Perruisseau-Carrier and his group is reviewed. From the experimental point of view, Prof. Perruisseau-Carrier determined the reconfigurable EM properties of graphene in different frequency bands and introduced self-biased graphene-based structures with enhanced performance and unprecedented...
The development of Green's Functions (GF) for structures including graphene layers is a keypoint for the design and analysis of future graphene-based antenna components. Their properties and computational challenges are presented and discussed within this contribution. Additionally, a novel computational technique that offers high evaluation speed and good accuracy for calculating such GFs is proposed...
