Abstract

In the present study, the nature of dielectric layer above metal layer in surface plasmon resonance sensor is investigated. The performance-defining parameters, i.e., shift in resonance angle, half width at half maximum, and minimum reflection intensity, are investigated according to the variation of refractive index (real as well as imaginary) of dielectric layer. Moreover, these parameters are investigated according to the thickness variation of the dielectric layer at different purely real as well as complex refractive index of the dielectric layer.
