PCT No. PCT/FR90/00112 Sec. 371 Date Oct. 17, 1990 Sec. 102(e) Date Oct. 17, 1990 PCT Filed Feb. 16, 1990 PCT Pub. No. WO90/09675 PCT Pub. Date Aug. 23, 1990.A microwave generator that uses an electron beam and the phenomenon of the oscillating virtual cathode, but makes it possible to obtain energy with improved spectral quality and conversion efficiency as compared with standard vircator generators. This is achieved by the separate use of the electrons coming from the virtual cathode (80), that is, transmitted electrons (80) or reflected electrons (81) to convert their kinetic energy into microwave energy (4). |
