多层球粒子彩虹光强分布特性研究

Scattering Intensity Distribution of Rainbow by a Multilayered Sphere

基于多层球Debye级数分解理论,计算了不同参数下多层球粒子一阶彩虹的光强分布,分析了多层球粒子的参数-折射率指数因子对多层球粒子的一阶彩虹主峰角位置的影响;同时根据多层球Debye级数分解理论,将多层球粒子的各阶彩虹进行分离,对不同特性散射结构的光强分布进行了研究,分析了各阶干涉强度对散射场的贡献。

This paper briefly introduces the Debye-series decomposition theory for rainbow scattering by a multilayered sphere.On this basis,the first-order rainbow light intensity distributions by a multilayered sphere with different parameters are calculated,and the effect of the exponential factor of the multilayered sphere refractive index on the angular position of the main peak of the first-order rainbow is numerically investigated.Each order rainbow by the multilayered sphere can be separated through use of the Debye-series decomposition theory,and its light intensity distribution and contribution to the interference intensity of the scattering field are further analyzed.
