We are developing optimization algorithms to extract the modeling parameters for different metals and dielectric materials. These parameters are required for defining those materials in the simulation model.
Investigation of Plasmonic Waveguides
We are investigating plasmonic waveguides with different geometries and constructed using different materials. The finite-difference time-domain method is being used for the simulation. The purpose of this project is to observe the characteristics of Surface-Plasmon-Polariton (SPP) through these waveguides and find optimum design for different applications.
Investigation of Nanoplasmonic Couplers
We are analyzing the performance of different dielectric materials as nanoplasmonic couplers. In order to achieve longer propagation of SPP mode, we are trying to integrate both dielectric and plasmonic waveguide on the same device in the simulation model.
Study of Corrugated Slow Wave Structures for Backward Wave Oscillator
We are analyzing different corrugated slow wave structures such as semi-circular, triangular, square etc. in an attempt to find an alternative structure which is easier to fabricate than sinusoidal corrugation and provides better temporal growth rate.
