In this work, the authors proposed a thin artificial structure that could give rise to the strong reduction of both radar wave reflection and infrared thermal emission. This is realized by the subtle combination of two specifically designed metasurface layers that control the infrared emission and microwave absorption, respectively. Our measurement shows that the fabricated sample could have wideband absorption from 3–8 GHz with attenuation efficiency larger than 90% up to incident angles of 30°. In the infrared atmosphere window, it gives a very low emission value of about 0.2. These results show that our sample is practically very promising for the application of a radar-infrared bi-stealth technology.
