Query: Friedel-Type Oscillations in the Problem of Skin Effect in Degenerate
  Collisionless Plasma   It is shown that a Friedel type oscillations accompany skin effect in
degenerate plasma of a metal. It was learnt earlier that Friedel oscillations
take place under charge screening in quantum plasma. However the nature of
Friedel oscillations is not in the quantum character of the plasma, but in the
features of degenerate Fermi distribution, namely, in its sharp transformation
into zero directly just the other side of the Fermi surface. This circumstance
leads to the Frieldel-type oscillations under anomalous skin effect.
