Fractal plasmonic metamaterials for subwavelength imaging (2009)
Huang, Xueqin, Ye, Dexin, Xiao, Shiyi, Huangfu, Jiangtao, Wang, Zhiyu, Ran, Lixin, ...
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-dimensional...
Sub-diffraction-limit Observation Realized by Nonlinear Metamaterial Lens (2009)
Wang, Zhiyu, Luo, Yu, Peng, Liang, Huangfu, Jiangtao, Jiang, Tao, Wang, Dongxing, ...
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-field distribution...
Second-Harmonic Generation and Spectrum Modulation by Active Nonlinear Metamaterial (2009)
Wang, Zhiyu, Luo, Yu, Peng, Liang, Huangfu, Jiangtao, Jiang, Tao, Wang, Dongxing, ...
The nonlinear properties of a metamaterial sample composed of double-layer metallic patterns and voltage controllable diodes are experimentally investigated. Second harmonics and spectrum modulations...
