Three-dimensional visible-light invisibility cloak
Bin Zheng, Rongrong Zhu, Liqiao Jing +8
The concept of an invisibility cloak is a fixture of science fiction, fantasy, and the collective imagination. However, a real device that could hide an object from sight in visibl…
Multifrequency superscattering from subwavelength hyperbolic structures
Chao Qian, Xiao Lin, Yi Yang +8
Superscattering, i.e., a phenomenon of the scattering cross section from a subwavelength object exceeding the single-channel limit, has important prospects in enhanced sensing/spec…
Bistable scattering in graphene-coated dielectric nanowires
Rujiang Li, Huaping Wang, Bin Zheng +3
In nonlinear plasmonics, the switching threshold of optical bistability is limited by the weak nonlinear responses from the conventional Kerr dielectric media. Considering the gian…

Concealing arbitrary objects remotely with multi-folded transformation optics
Bin Zheng, Hamza Ahmad Madni, Ran Hao +4
An invisibility cloak that can hide an arbitrary object external to the cloak itself has not been devised before. In this Letter, we introduce a novel way to design a remote cloaki…
Graphene induced mode bifurcation at low input power
Rujiang Li, Xiao Lin, Hongsheng Chen +3
We study analytically the plasmonic modes in the graphene-coated dielectric nanowire, based on the explicit form of nonlinear surface conductivity of graphene. The propagation cons…
