Mie散射计算的新改进

New Improvements for Mie Scattering Calculations

V. E. Cachorro, L. L. Salcedo

摘要:

提出了计算Mie散射量的新方法。他们是基于详细分析的各种来源的错误米氏计算和数学上的理由。基于这些改进开发的算法被证明是可靠和有效的,没有尺寸($x=2πR/λ$)或折射率($m=m_R-{\rm i}m_I$)限制,并且用户可以选择预先确定结果中所需的精度。它还包括一个新的和有效的方法来启动向下递归的贝塞尔函数。

英文摘要:

New improvements to compute Mie scattering quantities are presented. They are based on a detailed analysis of the various sources of error in Mie computations and on mathematical justifications. The algorithm developed on these improvements proves to be reliable and efficient, without size ($x=2πR/λ$) nor refractive index ($m=m_R-{\rm i}m_I$) limitations, and the user has a choice to fix in advance the desired precision in the results. It also includes a new and efficient method to initiate the downward recurrences of Bessel functions.
