A set of Mie functions has been developed in MATLAB to compute the four Mie
coefficients an, bn, cn and dn, efficiencies of extinction, scattering, backscattering
and absorption, the asymmetry parameter, and the two angular scattering func-
tions S1 and S2. In addition to the scattered field, also the absolute-square of the
internal field is computed and used to get the absorption efficiency in a way inde-
pendent from the scattered field. This allows to test the computational accuracy.
This first version of MATLAB Mie Functions is limited to homogeneous dielectric
spheres without change in the magnetic permeability between the inside and out-
side of the particle. Required input parameters are the complex refractive index, m=
m’+ im”, of the sphere (relative to the ambient medium) and the size parameter,
x=ka, where a is the sphere radius and k the wave number in the ambient medium.
