Example 1: Monodisperse Distribution (Single Wavelength) –Comparison with an alternative Mie Tool

This example presents a single-wavelength simulation for monodisperse spheres possessing a complex refractive index. The results from the Mie Simulator GUI demonstrate excellent agreement with Scott Prahl's Mie Scattering Calculator; minor discrepancies primarily attributed to rounding.

Simulation parameters:

Sphere Diameter: 1.0microns Refractive Index of Medium: 1.33 Real Refractive Index of Sphere: 1.5 Imaginary Refractive Index of Sphere: -0.5 Wavelength: 632.8nm Number Density: 1e8spheres/mm3 Number of Angles: 360 (dtheta = π/360 = 0.5˚)

Example 2: Polydisperse Distribution (Multi-Wavelength) – Scattering of Intralipid Phantoms

To demonstrate the tool's scientific utility, we characterize Intralipid 20%, a standard tissue phantom used in biomedical optics (DiNinni2011). Intralipid 20% (w/w) corresponds to a volume fraction of 0.227 (Aernouts2013). Following Raju2017, we assumed a mean particle diameter and standard deviation of 0.22 µm and 0.4 µm, respectively.

Simulation parameters:

Poly Disperse Distribution: Log Normal Mean Diameter: 0.22 microns Std. Deviation: 0.4 microns Number of Sph. Sizes: 101 Refractive Index of Medium: 1.33 Real Refractive Index of Sphere: 1.47 Imaginary Refractive Index of Sphere: 0 Wavelength: 600 nm to 1000 nm in 10 nm steps Volume Fraction: 0.227 Number of Angles: 360 (dtheta = π/360 = 0.5˚)
