Nanoscopy of surface polarization with oblique dipole orientations
V. G. M. Duarte, D. A. Miranda, D. F. P. Cunha +4
The boundary conditions imposed by confined dipoles with arbitrary orientation on surfaces are presented, extending the conventional in-plane (IP) and out-of-plane (OOP) treatments…
Electrical Spectroscopy of Polaritonic Nanoresonators
Sebastián Castilla, Hitesh Agarwal, Ioannis Vangelidis +13
One of the most captivating properties of polaritons is their capacity to confine light at the nanoscale. This confinement is even more extreme in two-dimensional (2D) materials. 2…
Magnetic-field-assisted transmission of THz waves through a graphene layer combined with a periodically perforated metallic film
Yu. V. Bludov, M. I. Vasilevskiy, N. M. R. Peres
We consider a graphene sheet encapsulated in a two-dimensional metallic grating and a substrate () and subjected to an external magnetic field (in Faraday con…
Impact of graphene on the polarizability of a neighbour nanoparticle: a dyadic Green's function study
Bruno Amorim, P. A. D. Gonçalves, M. I. Vasilevskiy +1
We discuss the renormalization of the polarizability of a nanoparticle in the presence of either (i) a continuous graphene sheet or (ii) a plasmonic graphene grating, taking into a…
Scattering of surface plasmon-polaritons in a graphene multilayer photonic crystal with inhomogeneous doping
Yu. V. Bludov, N. M. R. Peres, G. Smirnov +1
The propagation of a surface plasmon-polariton along a stack of doped graphene sheets is considered. This auxiliary problem is used to discuss: (i) the scattering of such a mode at…
Renormalization of nanoparticle polarizability in the vicinity of a graphene-covered interface
Jaime E. Santos, M. I. Vasilevskiy, N. M. R. Peres +2
We study the electromagnetic properties of a metamaterial consisting of polarizable (nano)particles and a single graphene sheet placed at the interface between two dielectrics. We…
Optical bistability of graphene in the terahertz range
N. M. R. Peres, Yu. V. Bludov, Jaime E. Santos +2
We use an exact solution of the relaxation-time Boltzmann equation in a uniform AC electric field to describe the nonlinear optical response of graphene in the terahertz (THz). The…
Unusual reflection of electromagnetic radiation from a stack of graphene layers at oblique incidence
Yuliy V. Bludov, Nuno M. R. Peres, Mikhail I. Vasilevskiy
We study the interaction of electromagnetic (EM) radiation with single-layer graphene and a stack of parallel graphene sheets at arbitrary angles of incidence. It is found that the…
Enhanced Optical Dichroism of Graphene Nanoribbons
F. Hipolito, A. J. Chaves, R. M. Ribeiro +3
The optical conductivity of graphene nanoribbons is analytical and exactly derived. It is shown that the absence of translation invariance along the transverse direction allows con…
Mechanism for graphene-based optoelectronic switches by tuning surface plasmon-polaritons in monolayer graphene
Yu. V. Bludov, M. I. Vasilevskiy, N. M. R. Peres
It is shown that one can explore the optical conductivity of graphene, together with the ability of controlling its electronic density by an applied gate voltage, in order to achie…
