Reply To: Farfield simulations on thin film, box of monitors

[Guilin Sun]

Farfield projection from dipole source is challenge, since the near fields spreads all over the space. Using the suggested box monitors (5 monitor) works fine, as it picks all the upper radiations.  This is from principle from physics. However I did not find any published papers describe how such box monitors work, except our example.

Not sure what your goal is. If you want to get the extraction effiicency from such thin film device, you can use stack function, which is analytical:
