Using the energy spectrum of a system made of graphene subjected to a linear barrier potential, we study the Goos-Hanshen shifts. The calculation is done by determining, in the first stage, the corresponding phase shifts via the transmission and reflection probabilities. Numerical analysis shows that the Goos-Hanshen shifts depend strongly on the incident energy, barrier height and width, and vary positively or negatively under suitable conditions due to the strong angular and wavelength dependencies of their reflected phase.
