I have a question about computing the energy flux through a plane. For a slab structure of air holes in solid dielectric, we expect a TE-like photonic band gap. For finding the Q of a point defect in this structure, I ran 3 separate MEEP simulations with source components of Ex, Ey, and Hz, respectively, corresponding to the field components of TE-like excitation. For each simulation, I got the same quality factor.
When I put a flux plane directly above the slab to determine the upward flux for such a structure, I am getting different upward flux values for the different source components used (again Ex, Ey, and Hz). In general, should the flux through a plane be affected by the source component used, as I seemed to observe? Time changing magnetic and electric fields generate electric and magnetic fields, respectively. In MEEP, we only set a single source component - are other field components computed and used to find the Poynting vector, etc (which depend on both E and H fields)? In general, I guess I don't understand why in MPB, we can choose to solve Maxwell's equations for a certain polarization (TE/TM/TE-like/TM-like), but in MEEP, we simply specify a source with a single E/H component for computations.
