Aa. Krokhin et al., ELECTROMAGNETIC-FIELD GENERATED BY A CHARGED-PARTICLE MOVING SLOWLY THROUGH A CONDUCTING MEDIA, Physical review. B, Condensed matter, 55(1), 1997, pp. 268-277
We calculate the spatial distribution of the electromagnetic (EM) fiel
d generated by the motion of a charged particle in a metal. Regimes of
weak and strong spatial dispersion are considered analytically, and i
n the intermediate case we give numerical results. It is shown that th
e spatial distribution of the EM field is characterized by a certain l
ength which plays the same role as the skin depth in the theory of the
skin effect in metals. In the region behind the moving particle the d
istribution of the EM field has the form of a ''wake.'' Inside this wa
ke the strength decays by a power law, and outside it decays exponenti
ally.
