Flat Optics for Polarization Structure Engineering from 2D to 3D

Advanced Optical Materials, EarlyView.
Metasurfaces have transformed polarization control by enabling precise engineering of complex polarization structures. This review explores their evolution from generating 2D polarization structures to shaping fully 3D polarization fields. By unlocking the unprecedented control over the polarization and spectral information of light, these advances ...

Phase Topology Stability of an Optical Vortex via an Electrically Controlled Twist‐Planar Oriented Liquid Crystal Fresnel Lens

Advanced Optical Materials, EarlyView.
A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems

Advanced Optical Materials, EarlyView.
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...
