摘要：
We designed a four-layer structured absorber (Ti-Si-SiO2-Ti) in the ultra-long-wave infrared band. The paper applies the bare Ti-SiO2-Si film to determine the approximate target band of the absorber, and combined with the coupling effect of the top double-ring structure, it greatly enhances the absorber's property, which can make the absorber absorb more than 90% in the range of 14.0-26.3 & mu;m in the ultra-long-wave infrared band. For the complex natural environment in practical applications, the absorber has excellent polarization independence and maintains excellent absorption in the incident environment from 0-60 & DEG;. & COPY; 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
