Raghuram Dharmavarapu

Name of Guide :Dr. Shanti Bhattacharya
Year of Joining: 2014
Research Topic:Micro Optical Meta elements for complex light generation
Position: MS-PhD Dual Degree Jointly with Swinburne University, Australia


  • Pursued B.Tech in Electronics and Communication at MGIT College.

Current Research:

* Design, Simulation, Fabrication and characterization of Metasurfaces for complex light generation. Metasurfaces are planar(2D) metamaterials with subwaveIength thickness. The modelling work is carried by using FDTD method and Python is used for data analysis. The physical devices are fabricated using standard semiconductor/CMOS processing.
