Large tunable negative lateral shift from graphene-based hyperbolic metamaterials backed by a dielectric

摘要

Large negative lateral shift from the graphene-based hyperbolic metamaterials (GHMM) backed by a dielectric is theoretically predicted. It is demonstrated that large negative lateral shift for TM polarized reflected beam can be thousands of wavelengths near the Brewster angle. The lateral shift can be tunable by Fermi energy. Numerical simulation results for Gaussian incident beams coincide with the theoretical results from the stationary phase method. The result may have potential application in the design of photoelectronic device and optical communication systems.
