| Abstract: | Graphene can be used as a platform for transformation-optics devices due to its tunability of conductivity. Besides conductivity, we show that the loss of graphene can also be controlled. Using this priority and taking the advantage of transformation optics, we realize the concept of electromagnetic “black hole” by using of a single-layer graphene. Numerical simulations demonstrate that the surface plasmon polariton waves incident to the “black hole” are bent towards the central area and absorbed by the inner core. The advantages of graphene-based “black hole” are its planar, isotropic, and nonmagnetic characteristics. |
