Influence of Adhesion layer on Performance of Surface Plasmon Resonance Sensor

The nature of dielectric constant and its thickness placed between metal layer and prism base is analysed. The attributes of reflectance curve which defines the performance of the surface plasmon resonance sensor are shift in resonance angle, minimum reflection intensity, and half width at half maxima. These attributes are plotted according to the refractive index (RI) and extinction coefficient (EC) of the adhesion layer or buffer layer placed between metal layer and prism base. Further, these attributes are plotted according to the thickness of adhesion layer at different combination of RI and EC.
