Optical activity of graphene-based chiral metasurface in THz frequency range
Abstract
In this paper the optical activity of two types of graphene-based chiral metasurfaces with two different variations of graphene inclusion positions was studied. The gammadion resonators of the unit cell were partly made of graphene. Three resonant frequencies of the metasurfaces in the frequency range of 0.1—0.5 THz were found. It is shown that the value of optical activity expressed in azimuth polarization rotation angle strongly depends on the chemical potential of graphene petals, as well as on the position of graphene inclusions
