A new type of optical sensing device based on artificial metamaterials

Over the past decade, electromagnetic metamaterials have become an extremely active field of research in both the physics and the engineering communities. Metamaterials gain their properties from their structure rather than directly from their composition and show the peculiarity of having an index of refraction at optical frequencies from negative to very high positive values. Researchers have now suggested a new type of optical sensing device based on artificial metamaterials with topological darkness.
