Sikdar Nanophotonics and Metamaterial Research Group
Indian Institute of Technology Guwahati
Department of Electronics and Electrical Engineering
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 tunable metadevices.
