Negative index metamaterials are metamaterials which have the capability to direct and regulate waves due to their negative refractive index. Metamaterial broadly refers to any synthetic material with unusual refractive properties, in this context. The application of negative index metamaterials involves blending objects with the environment, and this application is being actively developed in the laboratory. This on-going research is funded by several US government agencies, including DARPA, the United States Air Force and the United States Navy. The theory of negative index metamaterials was originally outlined in 1968, and it was confirmed by experiment in 2001. As a practical demonstration of the associated capabilities, a small object was hidden from view, appearing to be empty space, using negative index metamaterials in 2006. Furthermore, in the news, as early as May 2006, there was discussion about using negative index materials for military applications, at radar frequencies. For example, the beam would be directed around the electromagnetically secreted object, returned to their original trajectory, appearing as empty sky.
