Abstract

Réflecteur comportant une surface de réflecteur cintrée concave. La surface du réflecteur est formée par une membrane de réflecteur initalement plane, constituée par un matériau résistant à la traction dans toutes les directions de sa surface, laquelle membrane est déformée par application d'une surpression sur sa face antérieure ou d'une dépression sur sa face postérieure, afin d'obtenir une surface de réflecteur cintrée de façon continue. Application aux antennes, aux miroirs solaires et analogues.
