The most common materials in the world, including plastic, steel, glass or wood have distinct molecular and chemical properties that give them intrinsic qualities, such as strength, flexibility or transparency. But an entirely different class of materials, called metamaterials, are coming onto the scene.

Artificially engineered, these materials have unique geometries and physical structures that can manipulate any mechanical or electromagnetic wave that passes through them. Metamaterials can perform a host of futuristic tricks; they can absorb sound waves to produce silence, bend light to create an invisibility cloak and dampen seismic waves to safeguard a building against an earthquake.

Metamaterial applications are numerous, but here are five of the coolest.
