Kinetic theory of the fibrous and laminated structures of electron flows moving in plasma

The formation of fibrous and periodical laminated structures in a series of physical phemomena in the space and laboratory plasma due to the growth of an aperiodical instability is discussed. Using the kinetic equation for an electron flow with the temperature anisotropy and plasma with finite temperature it is shown that fibrous structure are formed by the drift of an electron flow or in the case when the longitudinal temperature exceeds the transverse one. Laminated structures appear only in case of an additional drift of the electron flow, the vectors of longitudinal and transverse velocities of the drift being located in the planes of the layers. Typical sizes of these structures have been estimated
