Shaping Electromagnetic Waves with Metasurfaces

This lecture explores the journey from controlling light propagation through scattering media to enhancing wireless communications using tunable metasurfaces. The instructor discusses the development of smart reflectors, the challenges of bringing lab concepts to market, and the applications of reconfigurable metasurfaces in RFID and millimeter-wave technologies. The lecture also covers the first demonstrations of Reconfigurable Intelligent Surfaces (RIS) in wireless communications and the future prospects of RIS in mmWave data transmission. Additionally, it delves into the disruptive technology of electronically steerable antennas based on metasurfaces, highlighting their unique properties and applications in satellite communication and 5G networks.
