On‐Chip Active High‐Q Slow Light Topological Cavities

Laser &Photonics Reviews, EarlyView.
A slow light topological cavity is presented, where the light confinement and the quality (Q) factor are controlled through engineered dispersion of the slow light waveguide mode and its group velocity, introducing a new degree of freedom to design high‐Q photonic cavities.

A Dual‐Programmable Metasurface with Duplex Beam Steering for Full‐Space Terahertz Communications

Laser &Photonics Reviews, EarlyView.
A dual‐programmable terahertz metasurface enables independent control of transmission and reflection beam steering. It breaks through the limitations in resonant tunability by polarization allocation with 2D‐electron‐gas tuning, enabling a single resonator to incorporate bidirectional operating modes.

Rough Quasi‐Conformal Mapping for Realizing Omnidirectional Light Wave Manipulation in Lower‐Index Meta‐Lens

Laser &Photonics Reviews, EarlyView.
A rough quasi‐conformal mapping strategy breaks the rigid geometric constraints of transformation optics. By trading perfect local angle preservation for a dramatically reduced refractive index, this design paradigm enables the creation of ultra‐flat, wide‐angle, and even omnidirectional lenses that are both high‐performance and manufacturable, opening

Results of a Round Robin Test for the Determination of Polarization Resistances on Differently Weathered Zinc Samples Using Gel Electrolytes

Materials and Corrosion, EarlyView.
Whether a top layer of corrosion products on zinc or galvanized steel protects the metal from further corrosion can be determined by measuring the electrochemical corrosion product layer resistance using an agar gel as the test electrolyte. The test standard DIN 50023:2024‐07 has recently been published.

Vapor Deposition of Polymer Structures: From 2D Surface Coatings and Surface Microstructures to 3D Building Blocks and Structural Monoliths

Macromolecular Rapid Communications, EarlyView.
This review discusses the progress of vapor‐deposited polymer structures, from simple thin films and surface microstructures to complex 3D architectures and monoliths. It covers fabrication methods, polymerization mechanisms, and processes for fabricating these structures. The applications of these polymers are discussed, focusing on device integration
