title = "Plasmonic planar antenna for wideband and efficient linear polarization conversion",
abstract = "The design of metasurfaces able to efficiently control the polarization state of an electromagnetic wave is of importance for various applications. We demonstrate both theoretically and experimentally that plasmonic planar L-shaped antennas can induce a 90{\^a} - rotation of the linear polarization of light with a nearly total efficiency in the infrared (3-5 μm). The nanoantenna geometry is engineered so that the polarization conversion occurs over a 1 {\^I}m-wide spectral band ([3.25-4.25] μm) with a mean polarization conversion efficiency of 95 \%. In order to validate a theoretical model describing the antenna behaviour, we investigate the polarization conversion effect as function of the incident and azimuthal angles.",
