In this paper, graphene has been used in combination with a nanoplasmonic crystal made of semicircular metallic grating, in order to creation surface plasmons. We study graphene absorption under the influence of plasmonic resonances according to geometric parameters and dielectric refractive index. The use of this structure increased the absorption of graphene up to 28.7% in the near infrared region and the spread of absorption spectrum in the visible and throughout the near infrared regions that this amount of absorption and spectral region are controlled by grating material, dielectric refractive index and geometric parameters.
