Abstract

Abstract Translated from French Dispositif permettant, par réflexion, de modifier la polarisation d'une onde électromagnétique incidente. Ce dispositif comprend deux éléments : un élément réflecteur espacé d'une distance déterminée d'un filtre de polarisation constitué par une plaque métallique (1) dans l'épaisseur de laquelle est pratiqué un réseau périodique bidimensionnel de fentes résonnantes (2) à la fréquence de fonctionnement. Application aux systèmes d'antennes microondes, notamment aux antennes du type Cassegrain. Device allowing, by reflection, to modify the polarization of an incident electromagnetic wave. This device comprises two elements: a reflective element spaced by a determined distance from a polarization filter constituted by a metal plate (1) in the thickness of which is practiced a two-dimensional periodic network of resonant slots (2) at the frequency Operating. Application to microwave antenna systems, in particular to Cassegrain type antennas.
