    Characteristics and Applications of Plasmonic Materials Alternate to Gold and Silver
    (Department of Electrical and Electronic Engineering(EEE), Islamic University of Technology(IUT),, 2022-05-30) Alvi, Rafiuddin; Shahriair, Toukir; Shohdy, Abdelrahman
    In our modern world, plasmonic materials are used in many scientific sectors. They are mostly used in chemical sensing, information processing, further size reductions, miniaturize optical components etc. Gold and silver are the conventional materials used in plasmonic materials. But these materials also have some problems regarding their characteristics. There are some unconventional materials that show similar characteristics. The real as well as the imaginary parts of the refractive index of these atypical materials employed in the doping element in the proposed model of COMSOL simulations can be obtained using the Lorentz-Drude model. From the simulations, transmittance vs wavelength graphs are generated which are compared to the outputs of gold and silver. A comparative analysis is included for a better insight.
