Then maybe you should study more and argue less.I don't see what acceleration of the field has to do with how fast its change will be felt at some distance away from it.
Yes, but that isn't what the paper you cited showed. The paper you cited was showing the aberration of forces, not the propagation of changes in the field (despite some confusion on the part of the authors - which is probably why the paper didn't pass peer review).The speed of propagation of the change is either always c or always instantaneous, regardless of the speed or acceleration of the field itself.
It is well known that the free propagation speed of changes in the EM fields is c. It is also well known that there is no aberration in the forces from a uniformly moving charge. Please study the lecture below and ask questions.
