以辐射传递理论和弥散介质理论为基础,采用Pikaia遗传算法建立了物质辐射特性反向计算模型,该模型方法可以计算物质的辐射特性参数(折射率和吸收因子)、特征频率以及高频介电常数,同时确保计算结果满足Kramers-Kronig关系.通过结合实验对流体水、固体二氧化硅以及二氧化钛薄膜的反向计算分析,证明该模型方法能够准确和快速地计算物质各辐射特性参数,具有广泛的应用价值.
Based on the theory of radiative transfer and the theory of dispersive medium, Picoia genetic algorithm is used to establish the inverse calculation model of material radiation characteristics. The model can calculate the radiation characteristic parameters (refractive index and absorption factor), the characteristic frequency and the high frequency dielectric Constants and ensure that the calculated results satisfy Kramers-Kronig relationship.By combining the experiments with the reverse calculation of fluid water, solid silica and titania films, the model method is proved to be accurate and fast to calculate the radiation parameters of materials with a wide range of The application value.
