Welcome to Sikdar Nanophotonics and Metamaterial Research Group (SNMG)
(17
Jun, 2022: Dr. Ashish Kumar Chowdhary is the first PhD student graduated from
the SNMG group with best thesis award) 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 |
