Ultra-broadband solar energy absorber based on Ti and TiN from visible to mid-infrared Open
In this work, a metamaterial absorber based on titanium (Ti) and titanium nitride (TiN) is proposed. Theoretical calculation by finite-difference time-domain (FDTD) method shows that the absorber could achieve a bandwidth of 3720 nm in the…

Dual-Channel Mid-Infrared Toroidal Metasurfaces for Wavefront Modulation and Imaging Applications Open
In this paper, we propose a dual-channel mid-infrared toroidal metasurface that consists of split equilateral triangular rings. The electromagnetic responses are analyzed by the finite-difference-time-domain (FDTD) method and temporal coup…

Tunable Dual-Broadband Terahertz Absorber with Vanadium Dioxide Metamaterial Open
A dual broadband terahertz bifunction absorber that can be actively tuned is proposed. The optical properties of the absorber were simulated and numerically calculated using the finite-difference time-domain (FDTD) method. The results show…

Tunable Triple Plasmonically Induced Transparency in Triangular Cavities Coupled with an MDM Waveguide Open
In this paper, a side-coupled triangle cavity in a plasmonic waveguide structure is proposed and numerically analyzed by the finite-difference time-domain (FDTD) method and coupled mode theory (CMT). Triple plasmonically induced transparen…
