Based on the pulse source in the Meep reference:
exp( ā iĻt ā (t ā t0)2 / 2w2),
omega is the inverse of the wavelength
t0= cutoff * w, temporal width.
w=temporal width.
I usually specify the frequency bandwidth df,
So I wonder the relation of the df and w since I know that product
is different by different definition. Which one is used in Meep?
This is documented in the Meep reference manual:
You can instead specify (fwidth x), which is a synonym for (width (/
1 x))
i.e. df = 1/w.
