Magnetoplasma Oscillations under Anomalous Skin Effect Conditions

Abstract

The frequency of magnetoplasma oscillations are calculated under anomalous skin effect conditions, $\mathrm{kl}>\mathrm{}1\mathrm{}$, $k$ being the wave number of the oscillation and $l$ the electron mean free path. In large magnetic fields such that ${\omega }_c\tau \gg 1$ it is found that for $\mathrm{kl}\ll {\omega }_c\tau$ the frequencies are only slightly modified, whereas for $\mathrm{kl}\gg {\omega }_c\tau$ the oscillations are so heavily damped as to be unobservable.
