All-optical Hall effect by the dynamic toroidal moment in a cavity-based metamaterial
Zheng-Gao Dong, Jie Zhu, Xiaobo Yin +3
Dynamic dipolar toroidal response is demonstrated by an optical plasmonic metamaterial composed of double disks. This response with a hotspot of localized E-field concentration is…
Optical toroidal dipolar response by an asymmetric double-bar metamaterial
Zheng-Gao Dong, J. Zhu, Junsuk Rho +4
We demonstrate that the toroidal dipolar response can be realized in the optical regime by designing a feasible nanostructured metamaterial, comprising asymmetric double-bar magnet…
Toroidal dipole response in a multifold double-ring metamaterial
Zheng-Gao Dong, Peigen Ni, Jie Zhu +2
The toroidal response is numerically investigated in a multifold double-ring metamaterials at the antibonding magnetic-dipole mode (i.e., antiparallel magnetic dipoles in one doubl…
Plasmonically induced transparent magnetic resonance in a metallic metamaterial composed of asymmetric double bars
Zheng-Gao Dong, Hui Liu, Tao Li +3
We demonstrate that the trapped magnetic resonance mode can be induced in an asymmetric double-bar structure for electromagnetic waves normally incident onto the double-bar plane,…
Enhanced sensing performance by the plasmonic analogue of electromagnetically induced transparency in active metamaterials
Zheng-Gao Dong, Hui Liu, Jing-Xiao Cao +4
The gain-assisted plasmonic analogue of electromagnetically induced transparency (EIT) in a metallic metamaterial is investigated for the purpose to enhance the sensing performance…
High-sensing properties of magnetic plasmon resonances in double- and triple-rod structures
J. X. Cao, H. Liu, T. Li +6
We numerically investigated the magnetic plasmon resonances in double-rod and triple-rod structures (DRSs and TRSs, respectively) for sensing applications. According to the equival…
