Momentum exchange between light and nanostructured matter [PDF]

, 2021
An object\u27s translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system\u27s motion.

Focus control of wide-angle metalens based on digitally encoded metasurface [PDF]

Based on the principle of super-symmetric lens with quadratic phase gradient transformation, combined with the principle of digital coding of metasurface, we propose a wide-angle coded metalens for focusing control in two-dimensional space. This metalens

Broadband imaging with one planar diffractive lens [PDF]

, 2018
We demonstrate imaging over the visible band using a single planar diffractive lens. This is enabled via multi-level diffractive optics that is designed to focus over a broad wavelength range, which we refer to as an achromatic diffractive lens (ADL). We

Ultrathin metasurface devices for phase and polarization control [PDF]

, 2019
Metamaterials are artificial materials, which consist of periodic or non-periodic structures of manmade “atoms” with a typical size of subwavelength scale. Benefiting from the freedom to tailor the properties of electromagnetic waves that are unavailable
