FEBI – Radiation boundaries E-Field measurement

  I simulate one only model with two differente setups.
  
  Model is about a window on a metal wall which radiates an EM field and powered by a waveguide.
  
  Frequency is 1GHz and I "measure" fields (electric and magnetic) at 1 meter distance (far field)
  
  First setup is composed of only one domain and RADIATION boundary.
  
  Second setup is decomposed into two domains with FEBI boundaries.
  
  Fields magnituds are two time bigger in the first setup (Radiation boundary) than in the second one.
  
  Any idea about the reason?
  
  At any case, thank you.
