In this work, we present the band diagram analysis of a polaritonic crystal fabricated by periodically modulating the optical conductivity of a graphene sheet, which can be implemented as a virtual mirror in a Fabry-Perot type plasmonic resonator. We explain how the observed band diagrams can be explained in relation to the reflection spectra of the polaritonic crystal that we studied in our previous work.
We design a tunable plasmonic resonator that may have applications in sensing and plasmon generation—our design uses graphene-based Bragg reflectors of periodically modulated conductivity. Specifically, we explore and utilize the ability to use an array of Gaussian conductivity gratings as fully reflecting mirrors for surface plasmon polaritons (SPPs) propagating along a two-dimensional graphene sheet sandwiched between two dielectric materials.
In this work, we have looked at the behavior of the SSVEP signals over 4 varying stimuli frequencies and 4 varying distances between the subject and the stimulus. It was found that the strongest SSVEP were elicited in the lower frequency range around 8Hz and a distance up to 100 cm can have a significant effect on the elicited SSVEP signals.

Final Year Research Project: An Empirical Study on the Consistency of Fitness Function Metrics.
Final Year Project: Implementation of SSVEP Based BCI for Emergency Health Care.
In this project, we developed a system that would assist the patients who have undergone severe spinal injuries and paralysis, in their day-to-day activities was developed. At the same time with this system, we can avoid the necessity of a 24/7 caretaker by the side of such patients. Contribution for the literature review, implementation of the electronic design and in MATLAB and analysis or results.
