This program is written to find the size of copper nanoparticles in colloidal form.

This program is coded with Python with the help of numpy, matplotlib.pyplot libraries.

The "pymiecoated" python library has been used to calculate the Mie coefficients of scattering and absorption.

1. Rakie.dat: Contains the complex refractive index of copper for different wave lengths (0.204 - 2.2 micro meter).
