Research interests

Gagan Kumar is a member of the following research group and research areas:

Research group

Laser and Photonics

Research areas

Terahertz Plasmonics and metamaterials, Guided Wave Devics, Ultrafast Spectroscopy.

Terahertz Photonics and Plasmonics lab, led by Dr. Gagan Kumar conduct research in plasmonics, metamaterials, guided wave devices, surface plasmon assisted enhanced Raman scattering and absorption etc. The research activities involve both theory and experiment with the aim to develop new devices and sensors with improved speed and sensitivity. In the ongoing projects, the primary research focus of the laboratory has been to demonstrate terahertz plasmonic devices using corrugated structures and explore near field coupling in terahertz metamaterials and sensors. Our research activities are currently supported by the Science and Engineering Research Board (SERB), Board of Research in Nuclear Sciences (BRNS)
