Hello,

When I use a DFTMonitor, I can display either the magnitude, real part or imaginary part of the complex E field.

I understand that this complex E(r,w) field is the fourier transform of the temporal electric field E(r,t), but according to this link : https://kb.lumerical.com/en/layout_analysis_monitor_data_complex.html , the real and imaginary part of E(r,w) are still taken at a given instant t.

Does anyone know how this instant t is chosen by the software ?

Thank you for any help on this
