The Mie Simulator GUI is an open source tool for calculating the characteristics of Mie scatterers. This user-friendly tool calculates the spectral dependence of the scattering coefficient, scattering cross section, reduced scattering coefficient, phase function, average cosine of the phase function, forward / backward scattering percentage and scattering matrix entries for a single or series of wavelengths. These calculations can be run for mono-disperse and poly-disperse distributions based on Lorentz-Mie solution. The tool is also capable of estimating fitting parameters from the reduced scattering coefficient curve and is limited to the characteristics of the far-field scattering pattern. Mie scattering algorithm in the simulator is based on the BHMIE code. For absorbing spheres, we considered complex refractive index definition (m_sphere = m_real – j m_imag) in van de Hulst's Light Scattering by Small Particles (1957) book. To learn Mie algorithm and other parameters in Mie Simulator GUI, read Bohren and Huffman's Absorption and Scattering of Light by Small Particles, (1983) book, Maetzler's research report and Scott Prahl's 'Mie Basics' web pages. The phase function calculation for a mixture of spheres is based on Gélébart et al's Pure and Applied Optics, 5 (1996) paper, and the reduced scattering power law fiiting functions are based on Steve L. Jacques's Phys. Med & Bio. 58 (2013) review paper.
