Extraordinary properties of light transmission through a small chiral hole in a metallic screen
Extraordinary properties of light transmission through a small chiral hole in a metallic screen
The true three-dimensional finite element numerical solution of Maxwell's equations shows that the propagation of light through a thin flat free-standing metallic screen containing a hole of twisted shape is sensitive to whether the incident wave is left or right circularly polarized.
The intensity map and polarization state of light are dramatically changed depending on the mutual direction of the hole's twist and the incident light's wave polarization handedness. We also observed a strong concentration of the transmitted field at the centre of the chiral hole when light in the object plane rotates against the twist of the investigated gammadion type structure.

Abstract
The true three-dimensional finite element numerical solution of Maxwell's equations shows that the propagation of light through a thin flat free-standing metallic screen containing a hole of twisted shape is sensitive to whether the incident wave is left or right circularly polarized.
The intensity map and polarization state of light are dramatically changed depending on the mutual direction of the hole's twist and the incident light's wave polarization handedness. We also observed a strong concentration of the transmitted field at the centre of the chiral hole when light in the object plane rotates against the twist of the investigated gammadion type structure.
