Collective electromagnetic mode in layered conductors

The transverse zero-sound wave in a one-component charged Fermi liquid with quasi-two-dimensional electron energy spectrum is considered in the framew ork of the Landau theory. In contrast to conventional metals, the electroma gnetic wave propagation in such media along the weak conductivity direction is possible even for low intensities of the Fermi-liquid interaction. The field distribution in the sample under unilateral excitation is determined, the wave impedance is calculated, and the possibility of observing the eff ect in the pulse mode is considered.
