Non-Universal Critical Behaviors in Disordered Pseudospin-1 Systems
A. Fang, Z. Q. Zhang, Steven G. Louie +1
It is well known that for ordinary one-dimensional (1D) disordered systems, the Anderson localization length diverges as in the long wavelength limit ($λ\rightarrow \inft…
Anomalous localization behaviors in disordered pseudospin systems: Beyond the conventional Anderson picture
Anan Fang, Zhao-Qing Zhang, Steven G. Louie +1
We discovered novel Anderson localization behaviors of pseudospin systems in a 1D disordered potential. For a pseudospin-1 system, due to the absence of backscattering under normal…
An effective medium theory for predicting the existence of surface states
Meng Xiao, Xueqin Huang, Anan Fang +1
We build an effective medium theory for two-dimensional photonic crystals comprising a rectangular lattice of dielectric cylinders with the incident electric field polarized along…
Low-threshold directional plasmon lasing assisted by spatially coherent surface plasmon polaritons
Yang Cao, Zeyong Wei, Wei Li +5
We theoretically propose directional, low-threshold plasmon lasing in both the near-infrared and visible wavelengths by utilizing spatially coherent surface plasmon polaritons on a…
Self-consistent calculations of loss compensated fishnet metamaterials
Anan Fang, Thomas Koschny, Costas M. Soukoulis
We present a computational approach, allowing for a self-consistent treatment of three-dimensional (3D) fishnet metamaterial coupled to a gain material incorporated into the nanost…
Lasing in metamaterial nanostructures
Anan Fang, Thomas Koschny, Costas M Soukoulis
A self-consistent computational scheme is presented for one dimensional (1D) and two dimensional (2D) metamaterial systems with gain incorporated into the nanostructures. The gain…
Optical anisotropic metamaterials: Negative refraction and focusing
Anan Fang, Thomas Koschny, Costas M. Soukoulis
We design three-dimensional (3D) metallic nanowire media with different structures and numerically demonstrate that they can be homogeneous effective indefinite anisotropic media b…
Self-consistent calculation of metamaterials with gain
A. Fang, Th. Koschny, M. Wegener +1
We present a computational scheme allowing for a self-consistent treatment of a dispersive metallic photonic metamaterial coupled to a gain material incorporated into the nanostruc…
Surface waves in photonic crystal slabs
Bingnan Wang, Weitao Dai, Anan Fang +4
Photonic crystals with a finite size can support surface modes when appropriately terminated. We calculate the dispersion curves of surface modes for different terminations using t…
