Electrical tunability due to coalescence of exceptional points in parity-time symmetric waveguides
Jin Wang, Hui Yuan Dong, Raymond P. H. Wu +2
We demonstrate theoretically the electric tunability due to coalescence of exceptional points in PT-symmetric waveguides bounded by imperfect conductive layers. Owing to the compet…
Non-reciprocal mu-near-zero mode in PT-symmetric magnetic domains
Jin Wang, Hui Yuan Dong, Chi Wai Ling +2
We find that a new type of non-reciprocal modes exist at an interface between two \emph{parity-time} () symmetric magnetic domains (MDs) near the frequency of zero ef…
Super-resolution image transfer by a vortex-like metamaterial
Hui Yuan Dong, Jin Wang, Kin Hung Fung +1
We propose a vortex-like metamaterial device that is capable of transferring image along a spiral route without losing subwavelength information of the image. The super-resolution…
One-way Tamm plasmon-polaritons on the interface of magnetophotonic crystals and conducting metal oxides
Hui Yuan Dong, Jin Wang, Tie Jun Cui
We demonstrate theoretically the existence of one-way Tamm plasmon-polaritons on the interface between magnetophotonic crystals and conducting metal oxides. In contrast to conventi…
Zeeman Splitting of Photonic Angular Momentum States in Gyromagnetic Cylinder
Kin Hung Fung, Jin Wang, Hui Yuan Dong +1
We show that under the presence of a static magnetic field the photon eigen-frequencies of a circular gyromagnetic cylinder experience a splitting that is proportional to the angul…
Zitterbewegung-like effect near the Dirac point in metamaterials and photonic crystals
Xiaohui Ling, Zhixiang Tang, Hailu Luo +4
We present a physical explanation of Zitterbewegung-like effect near the zero-refractive-index point in a metamaterial slab in this paper. Between the negative and positive refract…
