The Mie Simulator GUI is an open-source, user-friendly tool designed to calculate the characteristics of Mie scatterers. It determines various properties, including the spectral dependence of the scattering coefficient, scattering cross-section, reduced scattering coefficient, phase function, average cosine of the phase function, and forward/backward scattering percentage. Additionally, it calculates scattering matrix entries for single or multiple wavelengths. Based on the Lorentz-Mie solution, these calculations can be performed for both mono-disperse and poly-disperse distributions. The tool can also estimate fitting parameters from the reduced scattering coefficient curve, though its capabilities are limited to the characteristics of the far-field scattering pattern.
This GUI tool is based on the BHMIE code. For absorbing spheres, the tool uses the complex refractive index definition (msphere = mreal – j mimag) as described in van de Hulst's Light Scattering by Small Particles (1957) book. To understand the Mie algorithm and other parameters within the GUI, refer to, 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 page. Phase function calculations for mixtures of spheres are based on the work by Gélébart et al. in Pure and Applied Optics, 5 (1996). The reduced scattering power law fitting functions are derived from Steve L. Jacques's review paper in Phys. Med & Bio. 58 (2013).
