Significant enhancement of magneto-optical effect in one-dimensional photonic crystals with magnetized epsilon-near-zero defect
Zhiwei Guo, Feng Wu, Chunhua Xue +4
Nonreciprocal (NOR) transmission with magneto-optical materials plays a critical role in a broad range of applications, such as optical isolation, all-optical signal processing, an…
Actively controlling the topological transition of dispersion based on electrically controllable metamaterials
Zhiwei Guo, Haitao Jiang, Yong Sun +2
Topological transition of the iso-frequency contour (IFC) from a closed ellipsoid to an open hyperboloid, will provide unique capabilities for controlling the propagation of light.…
Experimental demonstration of the robust end state in a split-ring-resonator chain
Jun Jiang, Zhiwei Guo, Ya-qiong Ding +4
One of the fascinating topological phenomena is the end state in one dimensional system. In this work, the topological photonics in the dimer chains composed by the split ring reso…
Generating electromagnetic modes with fine tunable orbital angular momentum by planar topological circuits
Yuan Li, Yong Sun, Weiwei Zhu +5
Metamaterials made of periodic arrangements of electric permittivity and magnetic permeability and arrays of resonators can provide optic properties unexperienced in conventional m…
