Singular integral equations analysis of THz wave scattering by an infinite graphene strip grating embedded into a grounded dielectric slab.

We consider the scattering and absorption of a plane -polarized THz wave by an infinite periodic graphene strip grating embedded into a grounded dielectric slab. The problem is reduced to the dual series equations, which, in turn, are reduced to the singular integral equation with additional conditions. The numerical method of the solution is based on the Nystrom-type algorithm and has guaranteed convergence.
