DETAILED DESCRIPTION - Multi-layer graphene ring layer of two-dimensional adjustable heat invisible cloak comprises substrate layer, insulating spacer layer, graphene ring layer, control unit and energy supply unit. The adjustable two-dimensional thermal invisible cloak comprises graphene ring layer to x-y plane center as an axis. Each two graphene ring layer are arranged between insulating spacer ring layer isolation. The substrate layer in two-dimensional multi-layer graphene under the ring layer is used for bearing two-dimensional multi-layer graphene ring layer. The hidden target is placed in two-dimensional multi-layer graphene ring layer and center position. The substrate layer and graphene layer is in contact with ring. The substrate layer corresponding to each of graphene at ring layer is drilled with small holes. The small hole is internally provided with a wire. One end of the wire is connected in graphene ring layer. The other end sequentially passes through the control unit and energy supply unit is grounded. The temperature field and isotherm is restored to the original distribution.
