Multispectral Polarization‐Insensitive Graphene/Silicon Guided Mode Resonance Active Metasurfaces
Advanced Photonics Research, EarlyView.CMOS‐compatible graphene/silicon active metasurfaces based on guided‐mode resonance filters are investigated. Simulations reveal a high extinction ratio (>25 dB), a narrow linewidth (≈1.5 nm), and polarization‐insensitive operation. Multispectral mid‐infrared performance is achieved via geometrical scaling.

All‐Dielectric Metasurface‐Based Gap Waveguides
Advanced Photonics Research, EarlyView.Dielectric metasurface‐based waveguides (metawavegides) offer several advantages over conventional waveguides, making them ideal for integrated photonics. A design of a metawaveguide composed of a pair of dielectric metasurfaces is proposed, where each metasurface behaves as a wall of either a perfect electric conductor or a perfect magnetic conductor,

A Quadruped Piezoelectric Ultrasonic Actuating Robot with Foot‐Leg‐Trunk‐Integrated Structure
Advanced Robotics Research, EarlyView.This study proposes a novel foot‐leg‐trunk‐integrated quadruped piezoelectric ultrasonic actuating robot with small size and lightweight. A hybrid vibration mode combining the first‐order out‐of‐plane bending vibration of the trunk and the first‐order horizontal bending vibration of driving legs is designed to generate elliptical trajectories at foot ...

p‐Cu(OH)2/n‐SrTiO3 Heterojunction for Efficient Photocatalytic Hydrogen Production
Advanced Sustainable Systems, EarlyView.Improving the efficiency of photocatalysts in the hydrogen evolution reaction relies on developing cost‐effective co‐catalysts. This study focuses on p‐Cu(OH)2/n‐SrTiO3 heterojunctions for efficient hydrogen production. 1 wt.% Cu‐based co‐catalyst significantly enhances performance, achieving ≈3.5 times higher hydrogen production compared to pristine ...
