Abstract

Perfectionnement au procédé de balayage électronique utilisant des panneaux diélectriques déphaseurs comportant des fils à diodes permettant de rendre à volonté continus ou discontinus les fils conducteurs sur lesquels les diodes sont montées. Procédé consistant à perfectionner les réseaux de fils de ces panneaux dans lesquels les fils conducteurs continus destinés à rendre les panneaux adaptés pour une longueur d'onde déterminée sont utilisés pour alimenter en tension les groupes de diodes des fils à diodes. Applications de ce perfectionnement aux lentilles actives permettant le balayage électronique d'un faisceau hyperfréquence dans le plan perpendiculaire aux réseaux de fils.
