WebThe Shockley–Ramo theorem allows one to easily calculate the instantaneous electric current induced by a charge moving in the vicinity of an electrode.It is based on the concept that current induced in the electrode is due to the instantaneous change of electrostatic flux lines which end on the electrode, not the amount of charge received by the electrode per … WebWe compute the strain fields and the interactions between dislocations at the junctions of classical small-angle grain boundaries. It is shown that, in contrast with the results for infinite small-angle boundaries, there are always forces acting on the dislocations in the arrays that define the grain boundaries, and that there is also an excess elastically stored …
