Anisotropic 2D materials for tunable hyperbolic plasmonics
Andrei Nemilentsau, Tony Low, George Hanson
Motivated by the recent emergence of a new class of anisotropic 2D materials, we examine their electromagnetic modes and demonstrate that a broad class of the materials can host hi…
Directive Surface Plasmons on Tunable Two-Dimensional Hyperbolic Metasurfaces and Black Phosphorus: Green's Function and Complex Plane Analysis
S. Ali Hassani Gangaraj, Tony Low, Andrei Nemilentsau +1
We study the electromagnetic response of two- and quasi-two-dimensional hyperbolic materials, on which a simple dipole source can excite a well-confined and tunable surface plasmon…
Chiral plasmon in gapped Dirac systems
Anshuman Kumar, Andrei Nemilentsau, Kin Hung Fung +3
We study the electromagnetic response and surface electromagnetic modes in a generic gapped Dirac material under pumping with circularly polarized light. The valley imbalance due t…
Quantum plasmonic excitation in graphene and robust-to-loss propagation
George W. Hanson, S. A. Hassani Gangaraj, Changhyoup Lee +2
We investigate the excitation of quantum plasmonic states of light in graphene using end-fire and prism coupling. In order to model the excitation process quantum mechanically we q…
