5 May 2015 Plasmonic planar antenna for spectral and spatial manipulation of the polarization
Author Affiliations +
The ability to control the polarization state of an electromagnetic wave thanks to plasmonic metasurfaces is at the core of many various applications. We demonstrate both theoretically and experimentally that plasmonic planar L-shaped antennas can induce a 90°-rotation of the linear polarization of light with a nearly total efficiency in the mid-wavelength infrared. Then, we generalize these results with V-shaped antennas that can induce any rotation of the linear polarization by engineering the in-plane geometry of the antenna.
