DR. DEBABRATA SIKDAR
Dr. Sikdar is a young academic researcher with interests focused mainly on the emerging research areas of plasmonics and metamaterials. He specializes in developing theory, modeling and simulation of novel nano-optical devices and nanoplasmonic systems. He also actively collaborates with many experimental groups from India and abroad (Universities in UK, Australia, China, and Russia).
​
His academic background is a blend of electronics, physics, communication engineering, and plasmonics which has naturally led him to investigate the exciting state-of-the-art technological areas, such as surface plasmon based tuneable metadevices that involves light propagation through different media and light–matter interaction at the nanoscale.
​
This leads to designing novel artificial material composites or ‘metamaterials’ and metadevices that exhibit extraordinary ability to manipulate light or electromagnetic wave in general at the nanoscale.
​
He has pioneered many novel techniques in theory, modeling and simulation of light interaction with guided and scattering media, proposed new tuneable metadevices, and published over 40 research articles, one patent and one book chapter.
​
He is currently the Principal Investigator of the “Sikdar nanoplasmonics Group” (SnpG) based at the Department of EEE, IIT Guwahati.

MY LATEST RESEARCH
The first ever demonstration of ‘smart’ nanoplasmonic platform at oil/water interface that evolves from a transparent ‘window’ into a reflective ‘mirror’ with application of tiny voltage.
Similar to spotlights, these new cubic dielectric nanoantennas can generate ultra-narrow directional beams to focus light at a micro or nanoscale with precise control over direction and beam width.
