Abstract :
In this paper we propose a new application for metamaterials. We will show that it is possible to design a metamaterial screen that converts an incident linearly polarized plane wave into a circularly polarized wave. The geometry of the metamaterial defines if the rotation of the electromagnetic fields is clockwise or counter-clockwise with respect to the direction of propagation (i.e. if the polarization is LCP or RCP)
