Metamaterials definition
Web8 jul. 2024 · Metamaterials are materials not generally found in nature and having negative permittivity and permeability but are instead artificially medium with a negative index of refractive and structures that have properties that are either not or seldom found in natural material [ 1, 2, 3 ]. Web28 jul. 2024 · Metamaterials are smart materials that have a wide range of properties and can be so different from each other that there isn’t a definition for them, although what they all have in common is that they are from an artificial origin. This means that they aren’t found in nature and have been created by people. Mini positive point for humans!
