Bamboo‐Slip‐Inspired Conformal Reconfigurable Metasurfaces

Advanced Science, EarlyView.
Bamboo‐slip‐inspired conformal reconfigurable metasurface system. The structure is mainly composed of three parts, which are conformal metasurface, pattern reconfigurable antenna, and control components (such as Field Programmable Gate Array (FPGA)). Conformal metasurfaces draw inspiration from the design of ancient Chinese bamboo slips.

Topology‐Enabled Finite‐Band Absorption Framework Based on a Bioinspired Nested Dual‐Loop Architecture

Advanced Science, EarlyView.
A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and
