The tunable and enhanced Goos–Hänchen (GH) shift for TM-polarized reflected beam from the graphene-based hyperbolic metamaterials (GHMM) is theoretically investigated. It is demonstrated that the lateral shift of the reflected beam can be tunable by Fermi energy and thickness of dielectric, and the largest GH shifts can be hundreds of wavelengths due to the enhanced effect by the GHMM. The minimum...
In this paper, we proposed a cavity containing colloidal ferrofluids to enhance the Goos–Hänchen (GH) shifts of reflected and transmitted light beams. By optimizing the parameters of the cavity, the resonance inside the cavity was strengthened, and we obtained huge GH shifts. Magnetocontrolled negative GH shifts have been also analyzed. We found that a suitable cavity with optimized structural parameters...
