Abstract

We show that, weakly damped electromagnetic waves can propagate in highly anisotropic organic conductors with a multisheet Fermi surface, including both quasi-one-dimensional and quasi-two-dimensional topological elements, placed in a magnetic field. The simple analytical expressions for the collective modes spectrum in short- and long-wavelenth limits are obtained. The numerical analysis of the dispersion equations is presented.

PACS: 74.70.Kn Organic superconductors;
PACS: 72.15.Nj Collective modes (e.g., in one-dimensional conductors);
PACS: 76.40.+b Diamagnetic and cyclotron resonances.

Key words: organic conductors, collective modes, high-frequency resonance.
