I attached two pictures extracted from meep's outputs.
The first is mine, plotting the intensity (the square of the field)
in a certain time (for example the last time)
and the second is a picture plotted in a paper acclaiming that it is
extracted with meep output data .
I want to know how I can plot intensity profiles as the second
picture? what is its commands in meep?
I think the second is the Fourier transformed fields, isn't it?
would you mind helping me?
No, it looks like the second picture is outputting the spatial fields,
not a Fourier transform.
It's possible that they are outputting the total (E + H) energy
density and not just the electric field. Alternatively, it's possible
they are running with force-complex-fields? set to true so that the
energy density |E|^2 is a time average. I'm guessing that they do at
least one of these two things because their energy density in the
air(?) region after the end of the waveguide is not oscillatory.
Also, they are using a different color table (-c green), but I assume
you weren't asking about that.
