Maxwell's demon-like nonreciprocity by non-Hermitian gyrotropic metasurfaces
Wenyan Wang, Wang Tat Yau, Yanxia Cui +2
We show that Maxwell's demon-like nonreciprocity can be supported in a class of non-Hermitian gyrotropic metasurfaces in the linear regime. The proposed metasurface functions as a…
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…
Formation of Non-reciprocal Bands in Magnetized Diatomic Plasmonic Chains
C. W. Ling, Jin Wang, Kin Hung Fung
We show that non-reciprocal bands can be formed in a magnetized periodic chain of spherical plasmonic particles with two particles per unit cell. Simplified form of symmetry operat…
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…
