    Abstract: A microwave generator, which includes a housing having two mutually opposite electrodes which are separated via an electrode intermediate space which is filled with a dielectric, and with the electrodes having a spark gap between them, which breaks down in order to emit microwaves when a high voltage is applied. The electrode intermediate space (13, 13a, 13b) can be at least partially filled with a second dielectric (15, 15a, 15b), which has a different dielectric constant compared with that of the first dielectric (14, 14a, 14b) which is located between the electrodes (6, 7) in order to vary the microwave frequency, whereby the second dielectric (15, 15a, 15b) is held in a reservoir (17, 17a, 17b) which communicates with the electrode intermediate space (13, 13a, 13b).

    Abstract: 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.

    Abstract: A reflecting electron tube for producing high-power, high-frequency, monoomatic microwave pulses includes an anode which produces little or no ion flux when struck by electrons emitted from a cathode, and requires no applied, external magnetic field. An anode support holding the anode and a cathode shank which supports the cathode are positioned within a vacuum chamber such that the anode is closely spaced from the cathode. The anode support is connected to a pulsed high-voltage supply located external to the chamber. The anode is formed from a material which does not produce a significant amount of ion flux but does permit electrons emitted from the cathode to oscillate through the anode. Electrons oscillating in phase bunch together within the potential well of the system and emit microwave radiation.

    Abstract: A microwave generator is provided for generating microwaves substantially from virtual cathode oscillation. Electrons are emitted from a cathode and accelerated to an anode which is spaced apart from the cathode. The anode has an annular slit therethrough effective to form the virtual cathode. The anode is at least one range thickness relative to electrons reflecting from the virtual cathode. A magnet is provided to produce an optimum magnetic field having the field strength effective to form an annular beam from the emitted electrons in substantial alignment with the annular anode slit. The magnetic field, however, does permit the reflected electrons to axially diverge from the annular beam. The reflected electrons are absorbed by the anode in returning to the real cathode, such that substantially no reflexing electrons occur. The resulting microwaves are produced with a single dominant mode and are substantially monochromatic relative to conventional virtual cathode microwave generators.
