Photonic p-n Junction: An Ideal Near-Field Heat Flux Modulator
Deyu Xu, Junming Zhao, Linhua Liu
Using a pair of p- and n-type semiconductors separated by a nanoscale vacuum gap, we introduce an optoelectronics element prototype, "photonic p-n junction", as an analogue of the…
Photothermal behavior for two-dimensional nanoparticle ensembles: Multiple scattering and thermal accumulation effects
Minggang Luo, Junming Zhao, Linhua Liu +1
Light-assisted micro-nanoscale temperature control in complex nanoparticle network attracts lots of research interests. Many efforts have been put on the optical properties of the…
A Reconfigurable Active Huygens' Metalens
Ke Chen, Yijun Feng, Francesco Monticone +9
Metasurfaces enable a new paradigm of controlling electromagnetic waves by manipulating subwavelength artificial structures within just a fraction of wavelength. Despite the rapid…
Broad band invisibility cloak made of normal dielectric multilayer
Xiaofei Xu, Yijun Feng, Shuai Xiong +3
We present the design, fabrication and performance test of a quasi three-dimensional carpet cloak made of normal dielectric in the microwave regime. Taking advantage of a simple li…
Polarization modulation by tunable electromagnetic metamaterial reflector/absorber
Bo Zhu, Yijun Feng Junming Zhao, Ci Huang +2
We propose a polarization modulation scheme of electromagnetic (EM) waves through reflection of a tunable metamaterial reflector/absorber. By constructing the metamaterial with res…
Switchable metamaterial reflector/absorber for different polarized electromagnetic waves
Bo Zhu, Yijun Feng, Juming Zhao +2
We demonstrate a controllable electromagnetic wave reflector/absorber for different polarizations with metamaterial involving electromagnetic resonant structures coupled with diode…
