Abstract

In recent years, the research on radar and infrared compatible stealth has attracted much attention. In this paper, metamaterials are designed by means of theoretical calculation and modeling simulation. The entire structure consists of an infrared shielding layer (IRSL), a radar absorbing layer (RAL) and a backplane. The simulation results show that when the angle between the incident microwave and the normal of the metamaterial is in the range of 0-40°, the average absorption rate of the structure in the 7-27 GHz band is relatively stable and reaches more than 90%. In the infrared band, the emissivity of the structure is lower than 0.28 and 0.32 at 3-5 μm and 8-14 μm, respectively. In addition, through the rational design of structure and materials, the metamaterial not only achieves dual stealth functions of low infrared emission and broad microwave absorption, but also has high transparency and flexibility, providing a new method for the study of multi-band stealth materials.
