Metamaterial structure surface cement-based electromagnetic/infrared compatible stealth material
The invention discloses a cement-based electromagnetic/infrared compatible stealth material with a metamaterial structure surface. The structure sequentially comprises a foamed cement-based electromagnetic wave-absorbing substrate layer, a periodically-arranged metamaterial structure foamed cement-based wave-facing surface electromagnetic matching layer and a low-infrared-emissivity composite stealth coating on the wave-facing surface from bottom to top. Through the mode of combining the foam cement-based electromagnetic wave-absorbing material and the infrared stealth coating, the purpose of compatibility of electromagnetic wave absorption and infrared stealth performance is achieved, the minimum reflection loss RLmin value is as low as-65.98 dB, and the electromagnetic reflection loss RLlt is obtained; the composite material has the advantages that the effective bandwidth of-10dB can reach 14.77 GHz, the thermal insulation and infrared stealth performance (the infrared emissivity is as low as 0.16) is realized, the mass is light (the density is 0.1-1.0 g/cm < 3 >), and the composite material can be conveniently applied to civil and military buildings.
本发明公开了一种超材料结构表面水泥基电磁/红外兼容隐身材料。从下往上依次包括泡沫水泥基电磁吸波基底层、周期排布超材料结构泡沫水泥基迎波表面电磁匹配层和迎波表面的低红外发射率复合隐身涂层。通过泡沫水泥基电磁吸波材料与红外隐身涂层相结合的方式，实现了电磁波吸收与红外隐身性能兼容的目的，其得到了最小反射损耗RLmin值低至‑65.98dB，电磁反射损耗RL<‑10dB的有效带宽可达14.77GHz，同时还具有保温隔热和红外隐身性能(红外发射率低至0.16)，且质量轻(密度为0.1～1.0g/cm3)，便于在民用和军用建筑中应用。
