Abstract:   (952 Views)

In this paper, a metasurface is proposed based on a silver thin film containing an ordered array of L-shaped nanoholes. A left and right-handed circularly polarized light is normally incident onto the proposed structure and its reflection and transmission spectra are calculated. Our simulated results show that the designed metasurface is significantly sensitive to the left and right-handed circular polarizations. This structure can be used to determine whether the incident circularly polarized light is left-handed or right-handed. Furthermore, it can be used as a filter for this type of polarization. Also, the effects of changing the horizontal arm of the L-shaped nanohole and thickness of metasurface are investigated on the wavelength region at which sensitivity to the left and right-handed circular polarization occurs.

Keywords: Plasmon, Metasurface, Circular Polarization, Nanohole.
