The H-polarized wave scattering by the semi-infinite grating of graphene strips in the THz frequency range is considered. Graphene strips are modeled as zero-thickness resistive surface with conductivity obtained from the Kubo's formalism. The scattered field is represented as a sum of the field of currents on the strips of infinite periodic grating and correction field. The singular integral equation with additional conditions is obtained. The frequency dependences of the scattered field, as well as field distribution are presented, and the influence of the correction currents is discussed.
