This paper presents a structure design using metasurface to achieve infrared and microwave multi-spectrum compatibility through a single functional layer. The structure demonstrates microwave absorption and transparency in the visible light band. Experimental results validate theoretical predictions, offering reference for further research on compatibility technology and potential applications in stealth technology.
In the past, most of the structures that achieve infrared and microwave multi-spectrum compatibility are consisted of infrared shielding layer (IRSL) and radar absorption layer (RAL). This paper uses theoretical analysis, calculation, and simulation methods to design metasurface. The structure designed in this paper can achieve the effects of the two layers mentioned above through a functional layer. Through microwave absorption, a reflection effect of less than -10 dB is achieved in the range of 7.3-10.3 GHz. Besides, the structure is transparent in the range of visible light band. The infrared emission is 0.27 in atmospheric window denoted as 3-14 mu m. The experimental results are consistent with theoretical predictions and simulations. Our strategy has reference significance for broadening the method of multi-spectrum compatibility research, and it also has great potential in the application of multi-spectrum compatibility stealth technology.
