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. PhD Opportunities We are
currently looking for motivated and curious minds to join our laboratory as
PhD Students for exploring emerging areas of Integrated Nanophotonics, Plasmonics, and Metamaterials based Devices.
If you
are interested, please apply for the relevant Ph.D. position through the IITG Website. For any
queries, you can drop an email to deb[dot]sikdar[at]iitg[dot]ac[dot]in |
