Graphene Transverse Electric Surface Plasmon Detection using Nonreciprocity Modal Discrimination
We present a magnetically biased graphene-ferrite structure discriminating the TE and TM plasmonic modes of graphene. In this structure, the graphene TM plasmons interact reciprocally with the structure.

Tunable plasmonic enhancement of light scattering and absorption in graphene-coated subwavelength wires [PDF]
The electromagnetic response of subwavelength wires coated with a graphene monolayer illuminated by a linearly polarized plane waves is investigated. The results show that the scattering and extintion cross-sections of the coated wire can be dramatically

Graphene's Plasmon Prospects [PDF]
Applied Physics The length scales pertaining in optics and nanoelectronic circuitry differ by orders of magnitude. Combining the two offers the potential of exploiting the ultimate in transmission speed (the speed of light) with the tens of nanometers scale available to state-of-the-art ...

Hot plasmons make graphene shine
Bright hot plasmon emission is observed in graphene due to the ultrafast relaxation of hot carriers that were excited by femtosecond laser pulses of visible light.

Trapping and guiding surface plasmons in curved graphene landscapes
We demonstrate that graphene placed on top of structured substrates offers a novel approach for trapping and guiding surface plasmons. A monolayer graphene with a spatially varying curvature exhibits an effective trapping potential for graphene plasmons ...

Drift-Induced Unidirectional Graphene Plasmons [PDF]
Nonreciprocal photonic devices enable "one-way" light flows and are essential building blocks of optical systems. Here, we investigate an alternative paradigm to break reciprocity and achieve unidirectional subwavelength light propagation fully compatible with modern all-photonic highly-integrated systems.

Coated silicon carbide (SiC) thin films can efficiently enhance near-field radiative heat transfer among metamaterials. In this study, the near-field heat transfer among graphene–SiC–metamaterial (GSM) multilayer structures was theoretically investigated.

Investigating factors affecting loss reduction in graphene-based plasmonic structures [PDF]
In graphene-based plasmonic structures, the path length traveled by surface plasmon polaritons (SPP) or the propagation length of plasmons is very important.

Tunable nonlinear graphene metasurfaces
We introduce the concept of nonlinear graphene metasurfaces employing the controllable interaction between a graphene layer and a planar metamaterial. Such hybrid metasurfaces support two types of subradiant resonant modes, asymmetric modes of structured
