Hi Sahil,
As Figure 3 is FDTD simulation results validation. Normalized light scattering intensity distribution with scattering angle – comparison of simulation and analytical results. FDTD – Light scattering intensity with scattering angle for three values of the imaginary part of the refractive index of the extra-cellular medium: a) 0.00; b) 0.01; c) 0.05. Higher absorption in the extra-cellular medium increases the scattering intensity for larger values of the scattering angle.
And figure 4 is Light scattering intensity with scattering angle for three values of the imaginary part of the refractive index of the extra-cellular medium: a) 0.00; b) 0.01; c) 0.05. Higher absorption in the extra-cellular medium increases the scattering intensity for larger values of the scattering angle.
So, we can easily get the results using Finite-Difference Time-Domain (FDTD) method.
