The Cyclotron Waves in Layered Conductors

We have studied theoretically the propagation of electromagnetic waves in layered conductors placed in a strong magnetic field B ₀. It is shown that the wave process is very sensitive to the orientation of B ₀ with respect to the layers. The weakly damping modes with the frequencies near the cyclotron resonance frequency can propagate at orientations of the magnetic field vector, for which the drift velocity of charge carriers along the B ₀-direction is close to zero. The cyclotron waves spectrum is analyzed with regard to the Fermi-liquid interaction of electrons.
