Fig. 1: Design concept and photographs of metasurfaces and MTL integrated composites.

Photographs of the a RuO2/glass resistive paste, b upper metasurface, c lower metasurface, and d MTL integrated composites. Inset of (d): side view of the MTL integrated composites. e Structural and functional schematic of the MTL integrated composites. The composites integrate microwave absorption, thermal insulation, and load-bearing functions through seven functional layers.
