Is this periodic strucutre or isolate ?

For periodic structures, you will need to use plane wave and periodic BCs and use grating analysis to get results of diffraction: Diffraction grating

if it is isolated, you will need to use TFSF source to quantify the scattering: Mie scattering (FDTD)

you sais the illumination is non-polarized. Please refer to this link:

Polarization incoherence
