Ray trajectories for Alcubierre spacetime

Ray trajectories for Alcubierre spacetime

The Alcubierre spacetime was simulated by means of a Tamm medium which is asymptotically identical to vacuum and has constitutive parameters which are continuous functions of the spatial coordinates.Accordingly, the Tamm medium is amenable to physical realization as a nanostructured metamaterial.A comprehensive characterization of ray trajectories in the Tamm medium …
