Title
(EN) CONFIGURABLE MICROWAVE DEFLECTION SYSTEM
(FR) SYSTEME DE DEFLEXION CONFIGURABLE HYPERFREQUENCE
Abstract
(EN) The invention relates to a configurable system (1) for deflecting an incident microwave beam (Fine) having a wavelength within a range of wavelengths corresponding to microwave frequencies, including: first (C1) and second (C2) dielectric diffractive components that are each capable of rotating about a rotational axis Z, said deflection system (1) being capable of generating a microwave beam (F) by diffracting said incident microwave beam (Fine) onto said first and second components (C1, C2), said microwave beam (F) being directed at an angle on the basis of the angular positioning between said first (C1) and said second (C2) diffractive components, said first and second components (C1, C2) respectively having first and second periodic structures that have first and second periods (P1, P2), along a first and second axis (X1, X2), said first and second structures respectively including a plurality of first and second primary microstructures (MS1p, MS2p) respectively formed on first and second substrates (S1, S2) having first and second substrate refractive indices.
(FR) L'invention concerne un système de déflexion (1) configurable d'un faisceau hyperfréquence incident (Fine) présentant une longueur d'onde comprise dans une plage de longueurs d'onde correspondant aux hyperfréquences comprenant : -un premier (C1) et un deuxième (C2) composant diélectrique diffractif aptes à effectuer chacun une rotation autour d'un axe de rotation Z, -ledit système de déflexion (1) étant apte à générer un faisceau hyperfréquence (F) par diffraction dudit faisceau hyperfréquence incident (Fine) sur lesdits premier et deuxième composants (C1, C2), ledit faisceau hyperfréquence (F) étant orienté selon un angle fonction du positionnement angulaire entre ledit premier (C1) et ledit deuxième (C2) composants diffractifs, -lesdits premier et deuxième composant (C1,C2) présentant respectivement une première et deuxième structure périodique de première et deuxième période (P1, P2) selon un premier et deuxième axe (X1,X2), lesdites première et deuxième structures comprenant respectivement une pluralité de premières et deuxièmes microstructures primaires (MS1p, MS2p) formées respectivement sur un premier et un deuxième substrat (S1,S2) de premier indice et deuxième indice de réfraction substrat.
