Abstract

L'invention concerne des articles qui comprennent: une première couche présentant une pluralité de rangées d'un premier matériau s'étendant le long d'une première direction, les rangées étant espacées l'une de l'autre et un centre de chaque rangée adjacente étant séparé par une distance inférieure à la longueur d'onde ?; et une seconde couche disposée sur la première couche et comprenant un second matériau. La première couche transmet au moins environ 50 % du rayonnement de la longueur d'onde ? d'un état de polarisation incident sur la première couche, et réfléchit de manière spéculaire au moins environ 80 % du rayonnement incident de la longueur d'onde ? présentant l'état de polarisation orthogonal. La seconde couche est également configurée de sorte que l'article réfléchisse de manière spéculaire au plus environ 10 % du rayonnement incident présentant l'état de polarisation orthogonal.
