Metamaterials are artificial materials engineered to have properties that are not found in naturally occurring materials. These unique properties are achieved by designing the structure of the material at a scale smaller than the wavelength of the phenomena it interacts with. Metamaterials have a wide range of applications, including cloaking devices, super lenses, and antennas with improved performance. Research in this area is focused on developing new metamaterial designs, characterizing their properties, and exploring novel applications for these materials in various fields such as optics, acoustics, and electromagnetics.
