CALCULATIONS OF OPTICAL SCATTERING CROSS SECTION FOR COMPOSION A1_2O_3/MgO/C MICROSCOPIC PARTICLES

本文用米氏方法导出了三种组分构成的均匀球形复合微粒子光学散射截面的计算公式,并计算了复合微粒子Al_2O_3/MgO/C在特定红外光波波长下的光学散射截面。给出了复合微粒子中不同组分的介质层厚度与散射截面的关系曲线。最后对结果作了简单讨论。

An optical scattering cross section calculation formula is derived for homogeneous spherical microscopic particles of three components. Scattering cross sections for spherical composite microscopic particles Al2O3/MgO/C are computed. Curves for scattering cross section as a function of core particle radius and MgO Carbon layer thickness are given with discussions on results.
