HELICAL WAVES IN METALS WITH MAGNETOIMPUR ITY STATES OF ELECTRONS

The effect of magnetoimpurity electron states on helical electromagnet ic waves propagating through an electron-hole plasma of normal uncompe nsated metals is considered. The reconstruction of the spectrum of the se waves is found to occur in the vicinity of the resonance electron t ransitions between the Landau levels and magnetoimpurity ones and it i s followed by new branches of the spectrum. The spectrum and the dampi ng decrement of these waves in the vicinity of the frequencies of reso nance electron transitions are calculated. The distribution of electro magnetic field in the of metal volume is determined. The surface imped ance of a metallic half-space with magnetoimpurity states is calculate d. The impedance resonances at limiting frequencies of the spectrum he lical waves are observed.
