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…
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…
The Morse lens
Huanyang Chen
In this letter, we find that Morse potential (proposed about 90 years ago) could be connected to Coulomb potential (or Newton potential) and harmonic potential (or Hooke potential)…
Plasmon-polaritonic quadrupole topological insulators
Ying Chen, Zhi-Kang Lin, Huanyang Chen +1
Quadrupole topological insulator is a symmetry-protected higher-order topological phase with intriguing topology of Wannier bands, which, however, has not yet been realized in plas…
