Ultra‑Broadband Microwave Absorption and Programmable Multispectral Camouflage Enabled by Neural‑Network‑Driven Impedance‑Gradient Metadevices

Caption

  • An impedance-gradient metadevice for multispectral compatible camouflage was intelligently designed using the neural network.
  • The metadevice demonstrates excellent microwave ultra-broadband absorption (2–18 GHz), infrared thermal insulation (ΔT≈65 °C), low emissivity (0.38), and rapid visible color change (1–2 s).
  • The assembled device offers programmability and multimodality while also exhibiting impact resistance (~30,000 N) and environmental stability.
