“…In the considered frequency range, where the conductivity is given by a Drude term, the ribbon GMP modes are similar to those studied in stripes in two-dimensional electron gases arising in GaAs heterostructures. 13,[33][34][35][36][37][38][39][40] Those studies showed that the frequencies of the magnetoplasmon modes ω n (B) are given by a simple expression…”

Faraday Rotation Due to Excitation of Magnetoplasmons in Graphene Microribbons

A single graphene sheet, when subjected to a perpendicular static magnetic field, provides a Faraday rotation that, per atomic layer, greatly surpasses that of any other known material. In continuous graphene, Faraday rotation originates from the cyclotron resonance of massless carriers, which allows dynamical tuning through either external electrostatic or magneto-static setting. Furthermore, the rotation direction can be controlled by changing the sign of the carriers in graphene, which can be done by means of an external electric field. However, despite these tuning possibilities, the requirement of large magnetic fields hinders the application of the Faraday effect in real devices, especially for frequencies higher than a few terahertz. In this work we demonstrate that large Faraday rotation can be achieved in arrays of graphene microribbons, through the excitation of the magnetoplasmons of individual ribbons, at larger frequencies than those dictated by the cyclotron resonance. In this way, for a given magnetic field and chemical potential, structuring graphene periodically can produce large Faraday rotation at larger frequencies than what would occur in a continuous graphene sheet. Alternatively, at a given frequency, graphene ribbons produce large Faraday rotation at much smaller magnetic fields than in continuous graphene.

Dedicated to Ulrich Eckern on the occasion of his 60th birthday.The linear electromagnetic response of a uniform threedimensional electron gas to a longitudinal electric field is determined by the known Lindhard dielectric function qω . In this paper, we derive exact analytical expressions for the second-order nonlinear electromagnetic response of the electron gas. We calculate the second-order polarizability α (2) qω of the system and, within the self-consistent-field approach, the second-order response function, analogous to qω . The best conditions for the observation of the secondharmonic generation are analyzed. *

“…More recently, the focus of plasma-wave studies has shifted to much lower, microwave frequencies. [41][42][43][44][45][46] The microwave spectra of plasma waves have been studied in macroscopic disks, 41,42 stripes, 44,45 and rings. 43,46 Observation of the 2D plasmons at so low frequencies has become possible due to substantial improvement of quality of quantum-well samples.…”

We consider the scattering of an incident electromagnetic radiation on a two-dimensional ͑2D͒ electron layer with an imbedded metallic contact. We show that the incident wave excites in the system the 2D plasmon polaritons running along the 2D layer and localized near it, and electromagnetic waves reflected back from the system. The ratio of the energy transformed to the 2D plasmon polaritons and reflected back from the layer depends on the frequency and the value of a retardation parameter, which characterizes the importance of retardation effects. When the retardation parameter is large, the energy of the incident radiation is mainly reflected from the 2D electron system and the excitation of the 2D plasmon polaritons is less effective. The results obtained are discussed in connection with recent experiments on the microwave response of the 2D electron systems.
