In HFSS antenna sim, Is the reflected Power radiated or not?

where does reflected power go?

I have a question about how HFSS handles the power reflected off an antenna input port. Suppose the incident power is 1W and 0.95 W is accepted, does the reflected portion (namely |a|^2*|S11|^2) end up being radiated across the ABC boundary or where does it go? Is it killed of somehow?

Thanks in advance for your insights

where does reflected power go

I don't think the reflected power goes across the ABC boundary because I had a scenario where the incident power is 1.0 W, the accepted Power is 0.45 W, and the radiated Power is 0.43 W. If the reflected power were to be radiated, I would expect the radiated power for this case to be higher than 0.43 W. Although I don't think it is radiated, I still wonder how the reflected power is handled in HFSS.
