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-…
A Rigorous Analysis of Plane-transformed Invisibility Cloaks
Yu Luo, Jingjing Zhang, Hongsheng Chen +3
The electromagnetic characteristics of plane-transformed invisibility cloaks are quantitatively studied in this paper. We take elliptical cylindrical cloak as the example, and use…
Wave and ray analysis of a type of cloak exhibiting magnified and shifted scattering effect
Yu Luo, Jingjing Zhang, Hongsheng Chen +3
Ray-tracing exercise and full-wave analysis were performed to validate the performance of a new type of cloak composed of isotropic metamaterials. It is shown that objects inside t…
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…
