Method of analytical regularization in terahertz wave scattering and absorption by infinite gratings of graphene strips

Abstract

The plane wave scattering and absorption by an infinite flat graphene strip grating are studied in the THz range in the H and E-polarization regimes. Accurate numerical treatment is based on the dual series equations and the analytical regularization technique. In the H-polarization case, the dominant feature is the excitation of the surface plasmon resonances on each strip.
