This is reasonably described in the raether book. Refractive index of the prism, respectively, and denotes the wavelength of incident light. Simulated electric fields of the surface plasmon wave which appears at the interface between the metal thin film and dielectric layer are observed.

Kretschmann configuration is one among them. This niche of spr sensing has been especially exploited in biological sciences for the determination of binding constants and the identification of binding partners. The evanescent wave penetrates through the thin metal film, attached at the base of the prism, and triggers sp propagation at the outward surface of the metal. @article{vinogradov2018excitingsp, title={exciting surface plasmon polaritons in the kretschmann configuration by light beam.}, author={a. The two other configurations presented in figure above are based on the fact, that the light line in in dispersion figure can be in the third configuration (c), known as the kretschmann geometryiv, a thin metallic layer is formed on the substrate εo and acts itself as the spacer. Comsol simulation of the formation of surface plasmon polaritons in the kretschmann configuration. 1 kretschmann configuration in spr depicting the conversion of energy from light waves to surface plasmons via a gold/dielectric interface. In kretschmann configuration, metal thin film directly is deposited in the prism. A collimated gaussian beam is irradiated to the prism and the excited surface plasmons propagate along the sides. 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. 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. Excitation by atr kretschmann configuration otto configuration. Comsol simulation of surface plasmon polariton (spp) excitation using kretschmann configuration. Figure 1 illustrates the kretschmann spr configuration used in our numerical simulation and experiment. And then the thickness of metal is about 50 nm. I hope this paper by j. Simulated electric fields of the surface plasmon wave which appears at the interface between the metal thin film and dielectric layer are observed. There are several configurations of spr devices that are capable of generating and measuring surface plasmon resonance (1). 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. The refractive index of ito is larger than the optical fiber in visible spectral area (400 to 733nm), such that the structure is a typical kretschmann configuration surface plasmon. The kretschmann configuration uses the metal film on a glass block, whatever shape it has. 3 demonstrates clearly the sensing mechanism of the kretschmann configuration. Kretschmann configuration is one among them. Surface plasmon resonance (spr) is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light. In the first configuration, the csnps are considered as a homogeneous layer with effective permittivity given by. This result a shift in the dispersion relation (because the glass has a refractive index more than 1), and gives a possible resonance angle. Refractive index of the prism, respectively, and denotes the wavelength of incident light. This is reasonably described in the raether book. A prism is normally used to match the wave vectors between surface plasmons and the incident light. 2 a schematic of the practical kretschmann spr sensor configuration.
