| Abstract: | As an important means to weaken the performance of infrared imaging equipments or systems, artificially prepared infrared extinction materials have become the research object of many countries, and have achieved staged research results. The research status of artificially prepared infrared extinction materials is introduced from metal materials, expanded graphite, nano-materials, water-based foam, biomaterials and composite materials. The particle aggregation models of extinction materials such as particle and cluster, cluster and cluster are described. Several typical extinction calculation methods such as Mie scattering method, discrete dipole approximation method, T matrix method, and finite-difference time-domain method are introduced. According to the analysis, the infrared extinction materials prepared manually in the future will develop in the direction of long duration, low cost, various forms of release, environmental protection and non-toxic. |
