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.

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.
