Dynamic Manipulation of Infrared Radiation with MEMS Metamaterials

摘要: materials are fashioned from ‘artifi cial atoms’, which engineered to yield a specifi c response the electric and magnetic components of light, properties preserved in macroscopic medium fabricated their individual units. Electromagnetic achieved by metamaterials derive geometry unit cells, as opposed bandstructure makeup. Metamaterials thus bottom-up design paradigm for construction advanced hold great potential applications spanning electromagnetic spectrum. Although metamaterial have realized novel properties, some been diffi cult achieve with natural materials, ability dynamically control these responses real-time would offer signifi cant advantages enabling transition into state-of-the-art devices.
