Journal ArticleDOI
Broadband absorber with periodically sinusoidally-patterned graphene layer in terahertz range.
TL;DR: It is demonstrated that a broadband terahertz absorber with near-unity absorption can be realized using a net-shaped periodically sinusoidally-patterned graphene sheet, placed on a dielectric spacer supported on a metallic reflecting plate.
Journal ArticleDOI
Super-long photonic nanojet generated from liquid-filled hollow microcylinder.
TL;DR: Photonic nanojet from liquid-filled hollow microcylinder under a liquid immersion condition is numerically investigated based on the finite element method and physically analyzed with ray optics to show that, by simultaneously introducing the immersed liquid and filled liquid, the propagation beam is greatly flattened.
Journal ArticleDOI
Electrically Tunable Broadband Terahertz Absorption with Hybrid-Patterned Graphene Metasurfaces
TL;DR: A broadband terahertz absorber that is based on a hybrid-patterned graphene metasurface with excellent properties of polarization insensitivity, wide-angle, and active tunability that may have promising applications in teraherstz sensing, detecting, imaging, and cloaking is numerically demonstrated.
Journal ArticleDOI
Terahertz Absorber With Reconfigurable Bandwidth Based on Isotropic Vanadium Dioxide Metasurfaces
TL;DR: Simulated results show that absorptance peak can be tuned from 5% to 100% when the conductivity changes continually from $\text{10}\ {\Omega ^{ - 1}}{\text{cm}^{ - 1}$.
Journal ArticleDOI
Strongly Confined Spoof Surface Plasmon Polaritons Waveguiding Enabled by Planar Staggered Plasmonic Waveguides
TL;DR: The investigation results show the proposed PSPWs have excellent performance of deep subwavelength spoof SPPs confinement, long propagation length and low bend loss, as well as great design flexibility to engineer the propagation properties by adjusting their geometry dimensions and material parameters.
