THE OPTICAL CONSTANT SIMULATION OF SMOKESCREEN PARTICLE BASED ON KRAMERS-KRONIG RELATION

摘要

This paper deals with the numeric simulation of the refractive index of metals, which are used in smokescreen from the bands of visible light to infrared. The results are valuable to evaluation the obscure property of smokescreen or material selection. After the cubic spline treatment of the reflectance ratio data, the complex refractive indexes in visible light and infrared are calculated from the Kramers-Kronig analyzing. The precision of metal materials is satisfied and can be improved by extent data.
