| 摘要 |
The subject of the present invention is a very high-power microwave generator using the virtual cathode effect. The microwave generator (60) comprises an emitter (62) capable of producing electrons in a microwave output circuit (64, 66), the quantity of electrons emitted being sufficient to cause a regular variation in the electron density in the output microwave circuit, the circuit converting the kinetic energy of the electrons into microwave energy in a resonant mode, the electron emitter emitting the electrons in several regions of the microwave circuit that exhibit field extrema (Exa1, Exa2, Exa3) of the resonant mode.
