A Nearly Perfect Implementation of a Broadband Optical Null Media via Space‐Folding

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
A space‐folding optical null medium with impedance‐matching layers enables broadband directional wave projection and wavefront engineering. By tailoring the folding ratio and dilution ratio, the structure maintains near‐unity transmittance over 5–9 GHz.

Advances in High‐Temperature Microwave‐Absorbing Materials With Rare Metals: Preparations, Classifications, and Strategies

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT High‐temperature microwave‐absorbing materials (HTMAMs) are vital for the electromagnetic stealth of hypersonic aircraft and aerospace engines. Traditional carbon‐based or magnetic‐based absorbers suffer from oxidation, Curie‐temperature limitations, and impedance mismatch under extreme conditions.

One‐Step Fabrication of Multifunctional Superhydrophobic Surfaces With Photothermal and Electromagnetic Shielding for Anti‐Icing/De‐Icing

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Ice accumulation poses significant safety hazards and economic burdens across industrial sectors. Photothermal superhydrophobic coatings provide a practical yet promising solution. However, their fabrication typically requires complex multi step processing, limiting scalable implementation. Herein, we report a one step selective laser melting (

Wide‐Angle Domain Compatible Flexible Multispectral Stealth Metasurface for Visible Light, Laser, and Microwave

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
A flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...

High‐Isolation Nonreciprocal Sawtooth Grating via Quasi‐Bound States in the Continuum

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
We demonstrate a silicon sawtooth grating that simultaneously hosts three quasi‐BIC resonances. Leveraging the enhanced local field and directional coupling asymmetry, the device achieves a maximum nonreciprocal intensity ratio (NRIR) of 2.99 and an isolation exceeding 67 dB.
