Hello Meep users, I am interested in investigating the flux distribution over a plane outside a certain scattering structure. Is there a quick way to access the flux-region data usefully in order to produce a hdf5 output file showing the distribution of energy at a particular frequency over the plane? I am largely interested in the Poynting vector information but storage of individual field components would be useful too. I think I have seen it mentioned before on the newsgroup (in the context of near-to-far transforms) that the flux-region data is stored during runs in a form not really suitable for looking at after a run. I could of course write my own step function to do all this fairly easily (I notice from the reference guide that you can output the Poynting vector directly), but just wanted to make sure I wasn't reinventing the wheel computationally or missing the obvious (more than likely).
In a related point I know that unless you order it so to do, Meep will not store field data in a complex form. To calculate flux spectra however (E* x H) one must take the Fourier transform of the time-evolved fields which will result in complex forms for each field component. However when you save the flux-region data in hdf5 I see only 2 field components per plane. Can anyone shed light on what Meep is actually doing here to calculate the flux at each frequency? Thanks in advance.
