Research progress on artificially prepared infrared extinction materials and their extinction properties(Invited)

作为消弱红外成像设备或系统性能的重要手段,人工制备的红外消光材料成为各国争相研究的对象,并取得了阶段性的研究成果。从金属材料、膨胀石墨、纳米材料、水基泡沫、生物材料和复合材料等方面介绍了人工制备红外消光材料的研究现状,阐述了粒子-团簇、团簇-团簇等消光材料粒子凝聚模型,介绍了Mie散射方法、离散偶极子近似方法、T矩阵方法和时域有限差分法等几种典型的消光性能计算方法。分析认为,未来人工制备的红外消光材料将朝着持续时间长、成本低、施放形式多样和环保无毒等方向发展。

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.
