Abstract
L'invention concerne un procédé et un appareil permettant de générer et transmettre des impulsions sinusoïdales de haute fréquence, très courtes et très espacées d'énergie électromagnétique dans l'espace. Un transistor (TR3), un condensateur (C8) de charge et un inducteur (L1) sont couplés dans un premier chemin à boucle en série pour former un circuit de décharge. Une source (52) de tension de polarisation, le même condensateur de charge (C8), et une résistance (R13) de charge sont couplés en un second chemin à boucle en série pour former un circuit de recharge. La source de tension de polarisation est choisie afin de pouvoir polariser le chemin de conduction directe du transistor proche de son état de décharge disruptive. Le transistor est déclenché de manière intermittente dans son mode d'avalanche ou de décharge disruptive, et une antenne (56) est couplée à l'inducteur (L1) pour transmettre les impulsions d'énergie.
