A prism is normally used to match the wave vectors between surface plasmons and the incident light. And then the thickness of metal is about 50 nm. Furthermore, the angle of incidence required to excite an spp wave in a modified kretschmann configuration increases as the refractive index of the fluid increases. This result a shift in the dispersion relation (because the glass has a refractive index more than 1), and gives a possible resonance angle. Comsol simulation of the formation of surface plasmon polaritons in the kretschmann configuration. Figure 1(a) illustrates the classic kretschmann configuration 57 which is most frequently applied to excite spr.

Sambles will clear all you doubts. In the first configuration, the csnps are considered as a homogeneous layer with effective permittivity given by. An increase in the analyte refractive index modifies the plasmon's dispersion curve, and the resonance is obtained at a larger wavelength when the incidence angle is fixed. And then the thickness of metal is about 50 nm. Rather than sweeping through a range of coupling angles, as with the kretschmann prism, the fibre allows us to sweep through a number of coupling wavelengths.
