Title
(EN) DEVICE FOR GENERATION OF MICROWAVES
(FR) DISPOSITIF DE GÉNÉRATION DE MICRO-ONDES
Abstract
(EN)
The invention relates to a device for generation of microwaves comprising a virtual cathode oscillator (1) in a coaxial embodiment with an outer cylindrical tube forming a cathode (2) and connected to a transmission line (14) for feeding the cathode (2) with voltage pulses, and an inner cylindrical tube, at least partially transparent for electrons, forming a anode (3) and connected to a waveguide (13) for outputting microwave radiation generated by the formation of a virtual cathode (4) inside an area enclosed by the anode. Through the introduction of electrically conductive structures (5 and 6) a device for generation of microwaves is achieved that demonstrates higher efficiency and higher peak output.
(FR)
L'invention concerne un dispositif de génération de micro-ondes comprenant un oscillateur de cathode virtuelle (1) comportant de manière coaxiale un tube cylindrique externe formant une cathode (2) et connecté à une ligne de transmission (14) afin d'envoyer des impulsions de tension à la cathode (2), et un tube cylindrique interne au moins partiellement transparent pour les électrons, formant une anode (3) et connecté à un guide d'onde (13) afin d'émettre un rayonnement micro-onde généré par la formation d'une cathode virtuelle (4) dans une zone contenue par l'anode. Grâce à l'introduction de structures conductrices d'électricité (5, 6), on obtient ainsi un dispositif de génération de micro-ondes qui possède une plus grande efficacité et une plus grande sortie en termes de pic.
