Abstract(s) :

(Anglais) Transparent conducting electrodes which are not made from indium tin oxide (ITO), and which display a strong angular dependence are be useful for various technologies. Here, we introduce a tilted silver grating that combines a large conductance with a strong and angle-specific transmittance. When the light incidence angle matches the tilt angle of the grating, transmittance is close to the maximum along a very broadband range. We explain the behavior through simulations that show in detail the plasmonic and interference effects at play.
