The Magical World of Photonic Metamaterials
Metamaterials have opened a world of new possibilities that would have seemed like science fiction a decade ago, including subwavelength imaging, super lenses, perfect lenses and cloaking.
Starting in high school physics, we learn that light is a combination of electric and magnetic fields. As light propagates through matter, conventional materials only react to the electric field, resulting in most common optical effects, including refraction, diffraction and imaging.
