Geometric Phase in Optics: From Wavefront Manipulation to Waveguiding [PDF]

open access: yesLaser & Photonics Reviews, 2021
AbstractGeometric phase is a unifying and central concept in physics, including optics. As a matter of fact, optics played a pivotal role from the inception of this new paradigm, as some of the first experimental demonstrations have been carried out in optics.

Broadband and Dual-Polarized Terahertz Wave Anomalous Refraction Based on a Huygens’ Metasurface

open access: yesFrontiers in Materials, 2022
Terahertz wavefront manipulation is one of the key terahertz technologies. While few of the research works on terahertz wavefront manipulation has broadband and dual-polarized responses. Here a broadband dual-polarized Huygens’ metasurface is proposed to

Controlled light scattering of a single nanoparticle by wavefront shaping [PDF]

open access: yesPhys. Rev. A 106, 063502 (2022), 2022
Controlling light scattering by nanoparticles is fundamentally important for the understanding and the control of light with photonic nanostructures, as well as for nanoparticle scattering itself, including Mie scattering. Here, we theoretically and numerically investigate the possibility to manipulate nanoparticle scattering by wavefront shaping that ...
