Metamaterials

特許 権利維持 Metamaterials are artificial materials engineered to have properties that have not yet been found in nature. They are assemblies of multiple individual elements fashioned from conventional materials such as metals or plastics, but the materials are usually constructed into repeating patterns, often with microscopic structures. Metamaterials derive their properties not from the compositional properties of the base materials, but from their exactingly-designed structures. Their precise shape, geometry, size, orientation and arrangement can affect waves of light (electromagnetic radiation) or sound in a manner not observed in natural materials.
