Transparent matte surfaces enabled by asymmetric diffusion of white light
Hongchen Chu, Xiang Xiong, Nicholas X. Fang +5
The traditional wisdom for achieving transparency is to minimize disordered scattering within and on the surface of materials, so as to avoid translucency. However, the lack of dis…
Optical Brewster metasurfaces exhibiting ultra-broadband reflectionless absorption and extreme angular-asymmetry
Huiying Fan, Jensen Li, Yun Lai +1
Impedance mismatch between free space and absorptive materials is a fundamental issue plaguing the pursue of high-efficiency light absorption. In this work, we design and numerical…
Relaying Topological Interface States for Negative Refraction of Bulk Waves
Hongchen Chu, Ze-Guo Chen, Yun Lai +1
Topological notions in physics have become a powerful perspective that leads to the discoveries of topological interface states (TISs). In this work, we present a scheme to achieve…
Three-dimensional Electromagnetic Void Space
Changqing Xu, Hongchen Chu, Jie Luo +3
We report a realization of three-dimensional (3D) electromagnetic void space. Despite occupying a finite volume of space, such a medium is optically equivalent to an infinitesimal…
Breakdown of Maxwell Garnett theory due to evanescent fields at deep-subwavelength scale
Ting Dong, Jie Luo, Hongchen Chu +2
Deep-subwavelength all-dielectric composite materials are believed to tightly obey the Maxwell Garnett effective medium theory. Here, we demonstrate that the Maxwell Garnett theory…
Deep-Learning-Enabled Inverse Engineering of Multi-Wavelength Invisibility-to-Superscattering Switching with Phase-Change Materials
Jie Luo, Xun Li, Xinyuan Zhang +5
Inverse design of nanoparticles for desired scattering spectra and dynamic switching between the two opposite scattering anomalies, i.e. superscattering and invisibility, is import…
