miepython is a pure Python module to calculate light scattering by non-absorbing, partially-absorbing, or perfectly conducting spheres. Mie theory
is used, following the procedure in given by Wiscombe and validated against his results.
This code provides functions for calculating the extinction efficiency, scattering efficiency, backscattering, and scattering asymmetry. Moreover, a set of angles can be given to calculate the scattering for a sphere.
import miepython
m = 1.5 # index of refraction of sphere
x = 1.0 # dimensionless Mie size parameter
qext, qsca, qback, g = miepython.mie(m,x)
print("The scattering efficiency is %.3f" % qsca)
print("The backscatter efficiency is %.3f" % qback)
print("The scattering anisotropy is %.3f" % g)The scattering efficiency is 0.215
The backscatter efficiency is 0.187
The scattering anisotropy is 0.199
