Transverse current equivalence in Coulomb gauge All my problems come from the fact that I found in an article that the transverse current could be replaced at large distances by a perpendicular current, and that could be shown. The result they get is, moreover, correct. However, I asked one of the authors where could I see the proof, and he had no idea :S |

Transverse current equivalence in Coulomb gauge Indeed :D In Jackson's book I found a problem concerning my doubt (6.20 in the 3rd edition). After many calculations one finds that only perpendicular currents affect to pure radiation. Jackson doesn't comment this, and it surprises me because if you carry out the calculations this result is not at all obvious to get from the start (at least for me). He doesn't say anywhere I looked that this property can be generalised, and that's what I want to know. |
