Abstract: 

Complex dynamics of clectron beam with virtual cathode and distributed feedback is considered with the aid of numerical simulation. Characteristics of virtual cathode complex dynamics is investigated. For the system with connection through electron beam formation of the different types of autostructures is considered. It is proved, that complications of virtual cathode oscillation are connected with an increase of interaction between structures. For е system with connection through clectromagnetic fields (vircator — BWO) structures formation processes are investigated. It is demonstrated, that second structurc suppression by the interaction of virtual cathode with backwave fields makes possiblc controlling of output radiation characteristics.
