Switchable Hyperbolic Metamaterials With Magnetic Control
Wei Li, Zheng Liu, Xiaogang Zhang +1
A switchable hyperbolic material (SHM) is investigated, with which one can turn on or off the hyperbolic dispersion of the material via magnetic control. The SHM has simple structu…
Controlling spontaneous emission of a two-level atom by hyperbolic metamaterials
Zheng Liu, Wei Li, Xunya Jiang
Within the frame of quantum optics we analyze the properties of spontaneous emission of two-level atom in media with indefinite permittivity tensor where the geometry of the disper…
Confined one-way mode at magnetic domain wall for broadband high-efficiency one-way waveguide, splitter and bender
Xiaogang Zhang, Wei Li, Xunya Jiang
We find the one-way mode can be well-confined at the magnetic domain wall by the photonic bandgap of gyromagnetic bulk material. Utilizing the well-confined one-way mode at the dom…
Collimating lenses from non-Euclidean transformation optics
Kan Yao, Xunya Jiang, Huanyang Chen
Based on the non-Euclidean transformation optics, we design a thin metamaterial lens that can achieve wide-beam radiation by embedding a simple source (a point source in three-dime…
