The structure of most current multi-band stealth materials is very complex, making large-scale production and application difficult. We have demonstrated a structure that not only achieves multi-band stealth functionality but is also easy to produce and apply on a large scale. Contrast to previous approaches used in broadband range, this design exhibits a selective narrowband high absorption in the microwave range, marking a departure from conventional methods. The metasurface structure consists of an infrared shielding layer (ISL) and a microwave absorption layer (MAL), which respectively reduce the emissivity in the infrared band and the reflectivity in specific microwave bands. Simulation experimental data shows that the structure has excellent multi band stealth performance.
