摘要： The present application relates to a microwave wave generator with oscillating virtual cathode, with axial geometry, comprising at least one first reflector (F
1 ) positioned in a cylindrical waveguide (105) downstream of a thin anode (104), positioned at the entrance of the cylindrical waveguide (105), between a cathode (102) and the cylindrical waveguide (105). The device furthermore comprises a tight magnetic ring (112) of width (L
M ) along the longitudinal axis z, positioned externally around the cylindrical waveguide (105), between the thin anode (104) and the first reflector (F1).

摘要： The present invention relates to a device for generating microwaves with an oscillating virtual cathode, comprising a cathode (2), a thin anode (4) positioned at an inlet of a cylindrical waveguide (5), at least one first open reflector (9) and one last open reflector (9) located in the waveguide (5), which are transparent to electrons and capable of reflecting a microwave created by at least one virtual cathode generated in the waveguide (5), and a plurality of open reflectors (9) between the first and last open reflector (9) such that one reflector from the plurality has a radius RR(i+1) less than or equal to a radius RRi of a reflector from the immediately preceding plurality and the last open reflector (9) having a radius RRN less than a radius RR1 of the first open reflector.
