How exactly would one supply the energy needed for such a device? Nuclear Power?Physicists at the Boston College have recently managed to use new metamaterials to successfully control a beam of light employing a set of complex instructions. The achievement could have significant applications in the field of bending light around corners or other objects, and could contribute significantly to producing the soon-to-be-achieved invisibility cloak. The amazing thing about the research is that it makes the wave of light appear as if it is traveling in a straight line, when in fact it is bent around a structure, and then redirected to the other end, where it regains its original properties.
