Synergistic EMI Shielding: The Role of Nanoparticle Size and Alternating Bi‐Layer Coatings in Hybrid Fabrics

Advanced Materials Technologies, EarlyView.
This study fabricates three types of hybrid knitted fabrics: AgNPs of varying sizes are synthesized on the fabric, MXene nanosheets are applied via spray coating, and alternating AgNPs/MXene bi‐layers are added. The effects of particle size, material type, and bi‐layer structure on EMI shielding (≈60 dB), as well as breathability, air permeability, and

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

Advanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.
