cst farfield problem

Hi!

I am trying to solve the following problem: plane wave excites a sphere made of Ag placed in free space. Boundaries are opened, for Ag I use the drude model in optics.
I place a broadband farfield monitor and get a field depending on teta and phi in far zone.

2 questions:

1) The field I got - is it the sum of scattered + incident, or just scattered field?
2) How to make a graph Max(AbsE) vs frequency?

Thanks
