Definition of metamaterial in English:
metamaterial
noun ˈmɛtəməˌtɪərɪəlˈmedəməˌtirēəl
Physics A synthetic composite material with a structure such that it exhibits properties not usually found in natural materials, especially a negative refractive index.
the team began making these metamaterials and demonstrated several that scattered electromagnetic waves unlike any known materials
Example sentencesExamples
- So far researchers have only developed metamaterials that divert radar and microwaves - rather than light waves, which are the key to invisibility.
- The team used two different wedge samples so that waves would be incident on the metamaterial at two different angles.
- Left-handed materials - such as this "metamaterial" for microwaves - are reported to bend light in the opposite direction from normal materials, a property that might lead to a "perfect" lens.
- But the negative-index metamaterials that have been demonstrated are far more dispersive than typical materials.
- Such a small index does not mean the speed of light exceeds that of a vacuum: this rule of thumb breaks down in metamaterials.
