Experimental observation of Weyl points
Ling Lu, Zhiyu Wang, Dexin Ye +4
In 1929, Hermann Weyl derived the massless solutions from the Dirac equation - the relativistic wave equation for electrons. Neutrinos were thought, for decades, to be Weyl fermion…
Fractal plasmonic metamaterials for subwavelength imaging
Xueqin Huang, Dexin Ye, Shiyi Xiao +4
We show that a metallic plate with fractal-shaped slits can be homogenitized as a plasmonic metamaterial with plasmon frequency dictated by the fractal geometry. Owing to the all-d…
Sub-diffraction-limit Observation Realized by Nonlinear Metamaterial Lens
Zhiyu Wang, Yu Luo, Liang Peng +5
In this paper, we show by experiment that by covering a thin flat nonlinear lens on the sources, the sub-diffraction-limit observation can be achieved by measuring either the near-…
Second-Harmonic Generation and Spectrum Modulation by Active Nonlinear Metamaterial
Zhiyu Wang, Yu Luo, Liang Peng +5
The nonlinear properties of a metamaterial sample composed of double-layer metallic patterns and voltage controllable diodes are experimentally investigated. Second harmonics and s…
