Problems of non-linear dynamics and non-stationary behaviour of charged plasma interacting with secondary emission surfaces in crossed E×B-fields are discussed from the point of view of the investigation of new approaches for microwave electronic devices. Self-organisation of flows and formation of regular space structures due to the feedback at the emitting surface is shown. The results of computer simulations of electron clouds formation due to non-linear azimuthal instability inside coaxial systems embedded inside in external magnetic field under the condition of strong non-uniform secondary self-sustaining emission are described. The existence of quasi-stationary, rotating state of charged flow has been shown under conditions of conservation of full power and full momentum of the system. It is emphasised the dominant influence of a feedback due to non-uniform secondary emission on dynamics of plasma flow modulation and on arising of a leakage current across external magnetic field.
