Abstract

- La présente invention concerne une surface rigide réfléchissant les ondes électromagnétiques, notamment pour réflecteur d'antenne, blindage électromagnétique et guide d'ondes. - Selon l'invention, cette surface est constituée d'un entrelacs (7) de fils électriquement conducteurs (2, 3) qui sont constitués superficiellement d'un alliage métallique stable de diffusion assurant la solidarisation desdits fils entre eux et la rigidité de ladite surface.
