February 1-6, 2019 - San Francisco, CA Two invited talks at SPIE Photonics West February 7, 2020 - Davis, CA Invited seminar at UC Davis February 13, 2020 - Amsterdam. Netherlands Invited seminar at IoP at U Amsterdam February 20-21, 2020 - New York, NY Keynote talk at Graphene for US

Metasurfaces and Metamaterials We 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. Our MURI effort on this topic.

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.

Plenary talk at SPIE Optics & Photonics (2016)

Metamaterial Devices and Components Our 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 Nanocircuits We have put forward several innovative concepts to tailor emission, radiation, scattering, absorption and optical signal processing at the nanoscale, inspired to established concepts of RF antennas and circuits. Our MURI effort on this topic.
