Notice of Removal & Expression of Concern "Conventional Planar Chiral Structures to Realize Meta-Mirror with
Polarization Conservation and Circular Dichroism"
Abstract
Compared to simple mirrors, meta-mirrors have the ability to conserve
the polarization of incident light in reflection. In previous decade, a
lot of meta-mirrors designed for various applications. In this paper, a
meta-mirror is demonstrated to simultaneously conserve the polarization
of incident light and the circular dichroism. A conventional chiral
structure is used to design the meta-mirror in microwave regime. The
chiral structure is C2-symmetric (breaking the rotational and mirror
symmetries) for chirality inclusion into the meta-mirror. The design
methodology uses the principle of febry-perot cavity which includes a
sandwiched geometry. The substrate used to design the structure is Roger
5880 (a low-loss material at higher frequency bands) with copper
material for chiral structure and back reflector. Moreover, the
meta-mirror shows the insensitivity towards incident angle of light.
This meta-mirror can have a lot of applications in optical setup,
communication, chiral absorption, spin-dependent reflections etc.
