Mr Kishan Menghrajani
Postgraduate Researcher (Metamaterials CDT 2015)
My zeal for research towards Plasmonics sprung up by taking up project at VIT University. In my first year of M.Tech Nanotechnology, I worked on a project, which was “FDTD based simulation of surface plasmon resonance nano-lithography“ under the guidance of Dr. Gargi Raina and Dr. J.P.Raina, Director, Nanotechnology. I used FDTD Lumerical solutions software to simulate the different dimensions and materials, which are the causes for variations in the surface Plasmon phenomena.
I did my final year project at “Plasmonics and Metamaterial” group, Electrical Department, IIT Madras under the guidance of Dr. Ananth Krishnan. There, I worked on “Experimental study of Localized Surface Plasmon Resonances”. I observed SP [Surface Plasmon] ring in the Back Focal plane [Fourier plane] of the inverted microscope at the interface of metal-dielectric and I also observed LSPR [Localized Surface Plasmon Resonance] in the Back focal plane at the interface of metal nanoparticle on gold thin film.
After completing my Masters, I continued my research in the field of photonics and I was working at "Computational Photonics Lab", Indian Institute of Science (IISc) as a project associate. I was working on optical properties of chiral plasmonics and metamaterial nano-structures.
My first six month project is entitle,’ Localized excitonic and vibrational modes’, which will help me to understand my PhD project more.
The aim of the 6-month project will be to assess different fabrication approaches with the goal of producing structures that support localized surface resonances. The initial scope will be quite wide, with an exploration of materials supporting vibrational resonances as well as materials supporting excitonic resonances.
