Abstract
L'INVENTION A POUR OBJET UN TUBE A ONDES PROGRESSIVES DANS LEQUEL LA LIGNE A RETARD EST MAINTENUE EN PLACE PAR DES SUPPORTS ISOLANTS DONT LA FORME GEOMETRIQUE VARIE LE LONG DE L'AXE DU TUBE, AFIN DE SUPPRIMER CERTAINES OSCILLATIONS PARASITES. LA LIGNE A RETARD 4, HELICOIDALE ET CYLINDRIQUE D'AXE ZZ, EST MAINTENUE DANS UN FOURREAU 6 EGALEMENT CYLINDRIQUE D'AXE ZZ, PAR TROIS BARREAUX ISOLANTS 7, 8 ET 9 LONGITUDINAUX, DONT LA SECTION AUGMENTE LE LONG DE L'AXE DU TUBE, REALISANT AUSSI UNE AUGMENTATION DE LA CHARGE DIELECTRIQUE DE LA LIGNE 4.
