NANO-PHOTONICS & PLASMONICS

The objective of this research is to utilize metamaterial & metasurface concepts for the design of novel nano-photonic devices for applications such as communications, imaging and sensing.

In this thrust we are scaling down several of the microwave metadevices to the optical regime. Unique properties arise in this regime such as the excitation of surface plasmons in metals, the physical miniaturization of dielectric resonators and the kinetic inductance of metals.
