Metasurfaces and MetamaterialsWe have introduced the concept of nonperiodic metamaterials and metasurfaces with controlled variations along an axis of choice, providing new degrees of freedom for light manipulation at the nanoscale.
Cloaking and InvisibilityOne of the most exciting applications of metamaterials: our group has pioneered the use of plasmonic and mantle cloaks for drastic scattering suppression of radio-waves, infrared, matter, sound and light waves.
Introducing Cloaking (TACC video)
Metamaterial Devices and ComponentsOur group has proposed several exciting concepts to apply metamaterials and plasmonics for novel devices to manipulate, process and tailor radio-waves, THz, infrared, optical and sound signals.
Optical Nanoantennas and NanocircuitsWe have put forward several innovative concepts to tailor emission, radiation, scattering, absorption and optical signal processing at the nanoscale, inspired to the established concepts of radio-frequency antennas and circuits.
Welcome to Andrea Alù’s research group webpageAndrea Alù is an Associate Professor, and the David & Doris Lybarger Endowed Faculty Fellow in Engineering,in the Department of Electrical and Computer Engineering at The University of Texas at Austin in Austin, TX, USA. In 2015, he is also KNAW (Royal Netherlands Academy of Science) Visiting Professor at the AMOLF Insttitute in Amsterdam. He is affiliated with the Wireless Networking and Communications Group, an interdisciplinary center for research and education based in UT Austin with an emphasis on industrial relevance, and with the Applied Research Laboratories at UT Austin. His research interests span over a broad range of technical areas, including applied electromagnetics, nano-optics and nanophotonics, microwave, THz, infrared, optical and acoustic metamaterials and metasurfaces, plasmonics, nonlinearities and nonreciprocity, cloaking and scattering, acoustics, optical nanocircuits and nanoantennas.
