Title
(EN) FREUQENCY SELECTIVE SURFACE FOR THE FILTERING OF FREUQENCY BAND AND DESIGN METHOD THEREOF
(FR) SURFACE A SELECTIVITE DE FREQUENCE POUR LE FILTRAGE D'UNE BANDE DE FREQUENCE ET SON PROCEDE DE CONCEPTION
Abstract
(EN)
A Frequency Selective Surface (FSS) for the filtering of a frequency band and its design method are provided. The inventive FSS comprises a dielectric layer and a plurality of unit cells. The plurality of the unit cells are periodically arrayed on an upper end of the dielectric layer, each of the unit cells having a tri-pole and a ternary tree type loop connected without overlapping. In addition, the inventive method comprises the steps of bending a square shape loop at least once to obtain a meandrous square shape loop and adjusting a length of the meandrous square shape loop when forming unit cells in the FSS, and arranging the unit cells such that the FSS is comprised of geometrically identical unit structures or cells to tune a resonant frequency.
(FR)
L'invention concerne une surface à sélectivité de fréquence (FSS) destinée à filtrer une bande de fréquence et son procédé de conception. La FSS de l'invention comprend une couche diélectrique et une pluralité de cellules unitaires. Ces cellules unitaires sont périodiquement disposées en réseau sur une extrémité supérieure de la couche diélectrique, chacune de ces cellules unitaires possédant un tripôle et une boucle de type arbre ternaire reliés sans chevauchement. Par ailleurs, le procédé de l'invention consiste à plier au moins une fois une boucle de forme carrée en vue de l'obtention d'une boucle de forme carrée méandrique lors de la formation des cellules unitaires dans la FSS, et à agencer les cellules unitaires de sorte que la FSS soit constituée de structures ou cellules unitaires géométriquement identiques en vue du réglage d'une fréquence de résonance.
