Is there a way to calculate farfield phase profile of the field when simulating with 3D FDTD?

  I need to calculate the farfield phase profile of a waveguide output and looking for the syntax for lsf. I already have the farfield data.

  May I know how did you get the farfield data?
  As long as the far field has Ep and Es (in general, depending on how did you get them), you can extract the phase using
  phs=angle(Ep);
  Here Ep can be any field components, as it is complex field so it has a phase. Please refer this link angle .
