▎ 摘 要
A carpet cloak based on graphene is designed and realized by making an approximate hemisphere surface which behaves as a flat surface, and the performances of the cloak are simulated by finite element method. The cloak performs perfectly through tuning conductivity of the graphene. The incident wave can propagate on the curved surface without being disturbed, and an object under the curved surface will be cloaked It is indicated that graphene can be a platform for ''on-atom-thick" cloaks, and the proposed methods can be applied in the practical design.
