Abstract
An apparatus for redirecting physical energy includes a substrate defining a first boundary of a region, a first electrode defining a second boundary of the region, the second boundary disposed opposite to the first boundary, a second electrode adjacent to the first boundary for cooperating with the first electrode to apply a non-uniform electric field to the region, the non-uniform electric field having electrical field intensities simultaneously including a first electric field intensity and a second electric field intensity, and a layer of material disposed in the region, the layer having a variable index of refraction responsive to the electric field intensities of the non-uniform electric field, the variable index of refraction including a first index of refraction in response to the first electric field intensity and a second index of refraction in response to the second electric field intensity.
