Hello,
I would like to simulate scattering and absorption from a single gold nanosphere (or arrangement of spheres in the simulation area — dimer for example). I have found the tutorial explaining how to get the power transmission spectrum from an array of nanoparticles (https://optiwave.com/optifdtd-manuals/fdtd-nano-gold-particle/) using periodic boundary conditions, but I would like the response from a single particle, not an array. I can replicate this tutorial (with the 32-bit software), but when I try to change the boundary to APML, the transmission spectra looks incorrect (it does not go back to 1 at long wavelengths).
Any ideas? Also, is there a good way to convert the transmission spectrum into an absorption or scattering spectrum?
Thanks,
Jeremy
