Nanogroove array on thin metallic film as planar lens with tunable focusing
L. David Wellems, Danhong Huang, T. A. Leskova +1
Numerical results for the distributions of light transmitted through metallic planar lenses composed of symmetric nanogroove arrays on the surfaces of a gold film are presented and…
Effects of nonlocal plasmons in gapped graphene micro-ribbon array and 2DEG on near-field electromagnetic response in the deep-subwavelength regime
Danhong Huang, Godfrey Gumbs, Oleksiy Roslyak
A self-consistent theory involving Maxwell equations and a density-matrix linear-response theory is solved for an electromagnetically-coupled doped graphene micro-ribbon array and…
Asymmetrically filled slits in a metal film that split a light beam into two depending on its wavelength
Danhong Huang, L. David Wellems
By applying a scattering-wave theory, the electromagnetic response of an arbitrary array of multiple slits perforated on a metallic film and filled with different slit dielectric m…
Tracing Electron Beams in the Sun's Corona with Radio Dynamic Imaging Spectroscopy
Bin Chen, Timothy S. Bastian, Stephen M. White +4
We report observations of type III radio bursts at decimeter wavelengths (type IIIdm bursts) -- signatures of suprathermal electron beams propagating in the low corona -- using the…
Gap-modulated doping effects on indirect exchange interaction between magnetic impurities in graphene
Oleksiy Roslyak, Godfrey Gumbs, Danhong Huang
A dilute distribution of magnetic impurities is assumed to be present in doped graphene. We calculate the interaction energy between two magnetic impurities which are coupled via t…
Photon dressed electronic states in topological insulators: Tunneling and conductance
Andrii Iurov, Godfrey Gumbs, Oleksiy Roslyak +1
The surface bound electronic states of three-dimensional topological insulators, as well as the edge states in two-dimensional topological insulators, are investigated in the prese…
