Square Maxwell's fish-eye lens for broadband achromatic super-resolution imaging
Jue Li, Yangyang Zhou, Huanyang Chen
Broadband super-resolution imaging is important in optical field. To achieve super-resolution imaging, various lenses from superlens to solid immersion lens have been designed and…
Multiple super-resolution imaging from Mikaelian lens to generalized Maxwell's fish-eye lens
Yangyang Zhou, Huanyang Chen
Super-resolution imaging is vital for optical applications, such as high capacity information transmission, real-time bio-molecular imaging and nanolithography. Technology and meth…
Super-resolution imaging in absolute instruments
Yangyang Zhou, Zhanlei Hao, Pengfei Zhao +1
It has been shown that negative refraction makes a perfect lens. However, with little loss, the imaging functionality will be strongly compromised. Later on, it was proved that pos…
Switchable bifunctional metasurfaces: nearly perfect retroreflection and absorption at THz regime
Shan Zhu, Yanyan Cao, Yangyang Fu +4
Here we make use of vanadium dioxide (VO2) to design a bifunctional metasurface working at the same targeted frequency. With the increase of temperature, the functionality of the d…
Ancient Luoyang Bridge reveals a simple metagrating model in optics
Shiming Chen, Yangyang Zhou, Zhenyu Wang +1
The ancient Chinese bridge, Luoyang Bridge, has been revealed to obey similar laws to diminish waves, like an optical model, metagrating. Numerical simulations have been performed…
Enhanced third-harmonic generation induced by nonlinear field resonances in plasmonic-graphene metasurfaces
Yulian Liu, Shan Zhu, Qingjia Zhou +5
Nonlinear metasurfaces offer new paradigm for boosting optical effect beyond limitations of conventional materials. In this work, we present an alternative way to produce pronounce…
