Abstract

Surface plasmon resonance (SPR) is a physical property of the surface to investigate the important properties of optical behaviors for nanomaterial and biomaterial. It involves the excitation of electrons within a thin metal sheet by incident light at a specific angle, prompting them to propagate parallel to the surface. This sensitivity to external factors, such as changes in the refractive index of the surrounding medium due to molecular adsorption, underscores its potential as a detection mechanism for biomarkers and other analyses. Surface Plasmon Polaritons, non-radiative electromagnetic surface waves, are central to understanding this phenomenon. They are extremely sensitive to changes in this boundary as they spread along the interface between a conductor and an external medium, such as air or water. This sensitivity forms the basis for biosensors utilizing SPR. In the exploration of Surface Plasmon Polaritons, various models, including quantum theory and the Drudge model, are commonly employed. However, for practical applications in biosensing, a simplified approach often suffices. The resonant oscillation of the conduction electrons is formed at the interface of negative-positive permittivity content due to the incident polarized light. SPR sensors rely on many instruments to evaluate different materials’ absorption on the metal sheet. The authors investigated the surface frequency response of electromagnetic waves of various ranges on the surface of polar semiconductors at nanotubes theoretically by applying the Block Hydrodynamic Model by deriving a special dispersion relation between the frequency of plasmons and wave vectors in different dielectric mediums. It has a wide application in every field so authors have been focusing on increasing the sensitivity (S) of the SPR sensors employing novel sensor structures. Electromagnetic waves prevail at the periphery of two mediums of the loss and loss-free medium due to plasmons oscillation.
