Brilliant Future of Metamaterials Applications

Metamaterial (from the Greek word μετά meta meaning beyond or after and the Latin word material meaning matter or material) is a type of material engineered to have a property typically rarely observed in naturally occurring materials that is derived not from the properties of the base materials but from their newly designed structures. They are fashioned from multiple materials such as metals and plastics and are usually arranged in repeating patterns at scales that are smaller than the wavelengths of the phenomena they influence. Their precise shape geometry size orientation and arrangement give them their smart properties of manipulating electromagnetic acoustic or even seismic waves: by blocking absorbing enhancing or bending waves to achieve benefits that go beyond what is possible with conventional materials. Appropriately designed metamaterials can affect wave of electromagnetic radiation or sound in a manner not observed in bulk materials. Those that exhibit a negative index of refraction for particular wavelengths have been the focus of a large amount of research. These materials are known as negative-index meta-materials.
