Hi there Zemax community, 

I have some far-field information (Ex,Ey,Ez, Hx, Hy,Hz) for a point emitter which I have extracted from a FDTD simulation. I would like to now use these components in order to generate a source model for my FDTD point source using Zemax in non-sequential mode. 

As far as I understand it, I should use the Poynting flux instead of the field components for describing my source profile within Zemax right? 

Also, I could use some rope in finding some reference on how to use the extracted far-field information (which can be given in spherical coordinates) to set a distribution of rays, which represent the far-field energy flux for my FDTD source in non-sequential mode.

Any comments and help will be appreciated!
