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

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Methodology for Topological Interface Engineering in 2D Photonic Crystals

open access: yesAdvanced Photonics Research, EarlyView.
This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.
