Welcome to Sikdar Nanophotonics and Metamaterial Research Group (SNMG)

Our research group led by Dr. Debabrata Sikdar is dedicated to exploring and designing novel artificial material composites or metamaterials and metadevices that exhibit extraordinary ability to manipulate light or electromagnetic waves in general at the nanoscale. We are designing many novel techniques in theory, modeling and simulation of light interaction with guided and scattering media, and new tuneable metadevices.

(Interested UG/PG students can join the NPTEL course on Nanophotonics, Plasmonics, and Metamaterials.

The enrolment is open at: https://onlinecourses.nptel.ac.in/noc23_ee141/preview)

(17 Jun, 2022: Dr. Ashish Kumar Chowdhary is the first PhD student graduated from the SNMG group with best thesis award)
