Paint the surface with colors


Dear Lumerical team,

I want to ask about something in FDTD.
Can FDTD study the effect of paint the surface of structure with certain color?
If this option is already exist, how can I do it?



Hi @yara_elsebaai,

I’m not too sure to understand what you would like to do. FDTD Solutions is meant to model photonic devices with feature sizes on the order of the wavelength. I guess you could model the paint as a layer on top of the structure. You would need to know the thickness of the layer and the material properties of the paint (either the refractive index or the permittivity).

If you could give us some information about what you have in mind, we will be able to check if this is feasible with FDTD Solutions or not.


Thank you very much.
This is my need.
