Abstract

Frequency dependences of the linear dichroism coefficient (LDC) of linearly polarized TEM-waves of p- and s-polarization incident on a metasurface made of graphene nanoribbons (GNRs) are calculated for different values of the Fermi level of graphene in the THz range. It is shown that the GNR metasurfaces exhibit polarization-selective absorption of orthogonally polarized TEM-waves, while the operating frequency and LDC maximum are dynamically controlled by changing the Fermi level.
