Mie scattering look-up table covering a broad range of scattering parameters

We created a Mie scattering look-up table for a wide range of scattering parameters: 0.02<x<200, 0.2<m’<5 and 0<m”<5. The look-up table is very accurate, with an average relative error of <~0.1% and is up to 3500 times faster to evaluate than using analytical expressions for the Mie scattering coefficients. The data consists of Matlab® griddedInterpolant functions, packaged in a single ‘.mat’ file. The following scattering efficiencies are included in the dataset: total extinction (LUTQext), total scattering (LUTQsca), back-scattering (LUTQb) and forward scattering (LUTQf). For example, LUTQsca(2,1.5,0.01) evaluates the total scattering for x=2, m’=1.5 and m”=0.01. For fast execution speed, scattering coefficients for multiple values of x, m’ and m” must be evaluated with a single call by using vectors for x, m’ and m”.

NOTE: This is the latest and most accurate version. Please do not use previous versions as they are less accurate for small values of m”.
