August 7-9, 2020 - Online Invited talk at ThermoMeta 2020 August 23-27, 2020 - Online Keynote and invited talk at SPIE Optics & Photonics August 28, 2020 - Online Invited seminar for Xi'an Institute of Optics Sep. 28 - Oct. 1, 2020 - Online Several talks at Metamaterials 2020

Metamaterial-Enhanced Technology We have been exploring several ways in which metamaterials can advance real-life technology, from highly efficient opto- electronics (see our MURI effort) to energy harvesting, sensing, radio-wave and optical antennas and metasurfaces.

Cloaking and Invisibility One 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.

OSA Webinar (2020)

Non-Reciprocity and Topology Our group has been exploring several exciting concepts to exploit symmetry- breaking to enable extreme wave phenomena (see our MURI effort), including large non-reciprocity and topological metamaterials for light and sound.

Multi-Physics Metamaterials We have been exploring multi-physics platforms to extend the playground of opportunities enabled by metamaterials for technology, including opto-mechanical phenomena, thermal effects, plasmonics and polaritonics.
