Metamaterials are substances engineered to have properties that are not found in nature. They are made from assemblies of multiple elements fashioned from composite materials and are capable of manipulating electromagnetic waves, for example, to make things invisible.

One of the most important practical uses of metamaterials is in laser technology. An interdisciplinary group of researchers working at NUST MISIS under the guidance of Professor George Tsironis, a senior researcher at the NUST MISIS Superconducting Metamaterials Laboratory, studied a model metamaterial composed of semiconductor and dielectric layers that are thinner than the wavelength of incident radiation.
