A problem in far-field calculation

Hi there,
Now I have a problem when I do the far-field calculation in RF model. What I wanna do is to calculate the power outflow of an optical antenna in the far-field. But I found I only can get the electric field for the far-field calculation.
Does anyone know how to solve it?
Thanks and best regards,
Guanghao

I think you'll find some useful information on this thread: www.comsol.com/community/forums/general/thread/20515/
Also, a model I posted to the model exchange for a pyramidal horn antenna (www.comsol.com/community/exchange/192/) illustrates the use of Comsol's far-field quantities to compute antenna gain and far-field patterns.
Hope that helps.
