| Abstract |
Radio waves do not penetrate deep into the metal due to the high density of charge carriers in the metal. In the shorter-wave part of the spectrum, metals can be "transparent" only starting from ultraviolet, since the plasma frequencies in metals lie in the ultraviolet range. However, for a metal cooled to a low temperature and placed in an external magnetic field, the situation may change. Under these conditions, cyclotron orbits can be formed, and the relaxation time can significantly exceed the period of cyclotron motion of the charge carriers. For an electromagnetic wave with polarization normal to the induction vector of an external magnetic field, the exchange of energy with charge carriers in the metal turns out to be suppressed. Such a wave can propagate in the metal for relatively large distances (in comparison with the skin layer). In this connection, in electron storage rings at the azimuths, for example, of superconducting strong-field wigglers, with the magnetic field rise, the effect in the surface impedance change of the wiggler vacuum chamber metal can be manifested. This report is a brief review of some of results known in solid state physics applicable to these conditions and of interest to accelerator technology.
