“…SPR generated by external analyte detection techniques is demonstrated to be the best in the detection of an external refractive index, in DNA detection, and in bacteria [48,49]. Etched and tapered fiber sensors are used to detect organic pollutants and heavy metals [50]. GFET-based sensors have attracted attention because of genetic disease diagnosis.…”

This research proposes mathematical model for a plasmonic sensor using kinetic theory of Plasma with Vlasov equation. A Nano antenna cavity of a plasmonic material is driven by an input Electromagnetic wave which changes charge density and current flow in the cavity resulting in the change in Fermi distribution function of the charge particles. The results are achieved in terms of current density and conductivity solving Boltzmann Transport equation, Maxwell’s equations, and Taylor series expansion in terms of perturbed electric fields with linear Integro differential equations. The results are simulated using Matlab. The changes in current density and conductivity are validated by experimental analysis of Graphene plasmonic material using patch antenna with dielectrics substrates SiO2 and Al2O3.By varying the applied electric fields current changes at the output of the plasmonic antenna is analyzed using signal processing techniques. Wavelet Transforms are used to find the space scale behavior of the output signals such as current density variation, voltage variation, susceptibility change with sub band coding techniques in terms of wavelet coefficients.
