Analysis of the based-on graphene PIT metamaterials with THz wave

This paper proposes a plasma-induced transparency (PIT) metamaterial based on graphene disc and parallel graphene strips, which can achieve two different modes of PIT effect under the x and y electric field polarization modes. Through theoretical analysis, it is found that when the electric field is extended by x polarization, the PIT effect of bright-dark mode coupling can be realized, which is also the main discussion direction for this paper.
