Ultrathin multi-band planar metamaterial absorber based on standing wave resonances.
TL;DR: A planar waveguide model and a mechanism based on standing wave resonances to interpret the unity absorptions of ultrathin planar metamaterial absorbers with multi-band absorptions at desired frequencies can be easily designed.
Journal ArticleDOI
Ultrathin Dual-Band Metasurface Polarization Converter
TL;DR: In this paper, a dual-band metasurface based on a concentric rectangular arrangement was proposed to control the polarizations of both linearly and circularly polarized electromagnetic waves.
Journal ArticleDOI

TL;DR: By using the wave nature of surface plasmon polaritons, this work demonstrates that the Fourier transform can be implemented in a planar configuration with a minimal propagation distance of around 10 μm, resulting in an increase of speed by four to five orders of magnitude.
Journal ArticleDOI
On-chip discrimination of orbital angular momentum of light with plasmonic nanoslits
Shengtao Mei,Kun Huang,Hong Liu,Fei Qin,Muhammad Qasim Mehmood,Zhengji Xu,Minghui Hong,Dao Hua Zhang,Jinghua Teng,Aaron J. Danner,Cheng-Wei Qiu +10 more
TL;DR: A semi-ring plasmonic nanoslit to directly and spatially sort various OAM modes of light into ∼120 nm-spaced mode intervals on the metallic surface shows a viable solution to discriminate the OAM of light at the nano-scale and might lead to broad benefits across the fields of optical communications, plAsmonic physics and singular optics.
Journal ArticleDOI
Composition and accumulation of secondary carotenoids in Chlorococcum sp.
TL;DR: The advantages of tolerance to high temperature and extreme pH values, relative fast growth rate and ease of cultivation in outdoor system suggest that Chlorococcum sp.
