"WebThe reason is simple: by controlling the spatial variation of permittivity and permeability, one controls the local refractive index and thus the pathway of light in the medium. According to the Ferma’s principle of least time, a light ray propagating from a point A to a point B follows a path that minimizes the travel time. " - Permittivity and refractive index

WebThe relative permittivity is a measure of how strongly a material’s atoms or molecules polarize (i.e. how much charge separation is achieved) in response to an applied electric field. As an example, the relative permittivity of water for visible light is 1.8. The relative permittivity of vacuum is always 1. WebMay 9, 2024 · To validate the presence of the refractive index, a wedge-shaped metamaterial was designed. It is a widely used method—used to verify the left-handed behavior on Snell’s law [ 25 ]. For the wedge-shaped metamaterial, as shown in Figure 8 , eight unit cells in the x -axis and eight unit cells in the y -axis were placed.
