Abstract (en)
[origin: WO2014096728A1] 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.
