Enhancement of Goos–Hänchen effect in a prism-waveguide system with biaxially anisotropic metamaterial
چکیده انگلیسی

We study the mechanism of large lateral shift effect in a prism-waveguide coupling system where the guiding layer is composed of biaxially anisotropic metamaterial (BAM). We make use of stationary-phase approach to calculate the GH shift with different thickness of coupling layer and guiding layer, permittivity of coupling layer and imaginary parts of permittivity of BAM. Simulation results show that by the change of the above parameters, GH shift can be modulated sensitively. The physical explanation is given about these phenomenons and the proposed prism-waveguide system with BAM can be designed to realize different functions, such as thickness measurement, refractive index testing and absorption detection.
