•A simple periodic configuration for the excitation of surface plasmons polaritons (SPP) on a doped graphene sheet is presented.•A model taking into account the periodic spatial modulation of the graphene conductivity is proposed.•It is found that rather high absorption can be achieved with the presented structure.
We propose a model taking into account the periodic spatial modulation of a doped graphene sheet conductivity when it is placed in the vicinity of a dielectric grating. We then compute the absorption and study the excitation of surface plasmons on such a structure. We show that it is possible to excite surface modes leading to very high absorption. Our findings could be of interest in the design of graphene-based plasmonic devices and sensors working in the infra-red and the terahertz regions of the electromagnetic spectrum.
