How about "scattered"?  I think most people involved in this field would
refer to their work as a "scattering theory/model" (either Maxwellian or 
QED).  But it's not just semantics; I think you need to consider the 
"steady state" solution vs the "transient buildup" to that situation. 
(Can we treat this transient in our QED model?  I think we can - at least 
in principle - in the Maxwellian model.)
