Coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with symmetry
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
We demonstrate the coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with symmetry, which is composed of three interlacing triangular subla…
Pseudospin-Polarized Topological Line Defects in Dielectric Photonic Crystals
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
Electromagnetic topological insulators have been explored extensively due to the robust edge states they support. In this work, we propose a topological electromagnetic system base…
Quasi-Continuous Metasurfaces for Orbital Angular Momentum Generation
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
A quasi-continuous composite perfect electric conductor-perfect magnetic conductor metasurface and a systematic metasurface design process are proposed for the orbital angular mome…
Electrically Tunable Polarizer Based on Graphene-loaded Plasmonic Cross Antenna
Yuwei Qin, Xiaoyan Y. Z. Xiong, Wei E. I. Sha +1
The unique gate-voltage dependent optical properties of graphene make it a promising electrically-tunable plasmonic material. In this work, we proposed in-situ control of the polar…
Orbital Angular Momentum Generation and Detection by Geometric-Phase Based Metasurfaces
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
We present a comprehensive review on the geometric-phase based metasurfaces for orbital angular momentum(OAM) generation and detection. These metasurfaces manipulate the electromag…
Detection of Orbital Angular Momentum with Metasurface at Microwave Band
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
An orbital angular momentum (OAM) detection approach at microwave band is proposed. A transmittance function is exploited to model a transmissive metasurface. Then the metasurface…
