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 (

Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4572-4585, November 2026.
ABSTRACT This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture material properties.

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.

Terahertz Metamaterial Absorbers

Advanced Materials Technologies, 2021
Abstract Terahertz metamaterial absorbers (TMAs) can efficiently absorb electromagnetic wave in the range of 0.1–10 THz based on the tunable electromagnetic properties of artificially designed unit cells. TMAs can achieve perfect absorption, as well as broad band absorption. Specifically, TMAs can break the thickness limit of a device

Metamaterial saturable absorber mirror

Optics Letters, 2013
We propose a metamaterial saturable absorber mirror at midinfrared wavelengths that can show a saturation of absorption with intensity of incident light and switch to a reflecting state. The design consists of an array of circular metallic disks separated by a thin film of vanadium dioxide (VO(2)) from a continuous metallic film. The heating due to the
