The research in our group is focused on the physics and engineering of fields and waves and the various features and characteristics of wave-matter interaction in metamaterials and metasurfaces. Under this umbrella of research interest, there are several research themes that we explore extensively. Some of these themes are listed below.
Metamaterials, Metasurfaces, and Plasmonics
Metamaterials, as specially designed structures, provide useful platforms to manipulate and sculpt waves and fields for achieving unprecedented functionalities.
Quantum Metaphotonics and Nanoscale Optics
Exploring how metastructures can affect the light- matter interaction at the nanoscale provides useful roadmaps about how some of the quantum features of light can be engineered by these special platforms.
ENZ, MNZ, and EMNZ Structures
Extreme-parameter composites such as epsilon-near-zero (ENZ), mu-near-zero (MNZ), and epsilon-and-mu-near-zero (EMNZ) structures, offer “extreme” scenarios in electrodynamics of material media.
Modularized Nanophotonics, Optical Metatronics and Informatic Metastructures
Optical metatronics, as the nanoscale optical circuit paradigm with modularized (“lumped”) optical circuit elements, brings the notion of electronic circuitry into the field of nanophotonics. This allows modularization of light-matter interaction at the nanoscale and provides the methodologies and approaches to envision “informatic metastructures” that “can do math with light”- with the goal of nanoscale information processing
Mid-IR wave interaction with the graphene exhibits exciting optical features that pave the way towards the possibility of one-atom-thick optical devices and components.
Breaking time-reversal symmetry in photon flows is one of the exciting features in light-matter interaction with potential applications in integrated nanophotonics.
Sensing and Imaging Inspired by Eyes of Certain Animal Species
Inspired by the eyes of species that can “see” polarization of light, various techniques and methodologies are being added to the tool boxes of sensing and imaging science.
