Abstract
We report the observation of the Goos-H\"anchen effect in graphene via a weak value amplification scheme. We demonstrate that the amplified Goos-H\"anchen shift in weak measurements is sensitive to the variation of graphene layers. Combining the Goos-H\"anchen effect with weak measurements may provide important applications in characterizing the parameters of graphene.
