      Some properties of vortices in layered superconductors and superconducting structures with the Josephson interaction between S-layers are studied theoretically. The Josephson vortex lattice is formed in the system if the magnetic fieldHe is parallel to the layers. Long-wave oscillations of this lattice have a sound-like spectrum; the velocity of “magnetic sound” propagating across the layers is small and diminishes with increase ofHe. Using an analogy with electron-hole plasma in semiconductors, we investigate also the behaviour of the layered structure in the fieldHe perpendicular to the layers at temperatures close to the Kosterlitz-Thouless transition temperatureTKT. The spatial dependence ofH(r) and the impedance of the system are determined atT>TKT.
