What are metamaterials and metasurfaces? Definition, properties and applications
Metamaterials are artificially crafted composite materials that derive their properties from internal microstructure, rather than chemical composition found in natural materials. By engineering the arrangement of atoms into a desired architecture or geometry, metamaterials can be endowed with properties and functionalities unattainable in natural materials
