The kretschmann configuration uses the metal film on a glass block, whatever shape it has. 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. Figure 1(a) illustrates the classic kretschmann configuration 57 which is most frequently applied to excite spr. @article{vinogradov2018excitingsp, title={exciting surface plasmon polaritons in the kretschmann configuration by light beam.}, author={a. This is reasonably described in the raether book. Kretschmann configuration of spr gas sensing method. The metal that usually used is silver, gold and aluminum.

The planar multilayer sensor structure, based on the kretschmann and surface plasmon coupled emission (spce) configurations, is coupled to a periodic array of these nanoparticles. This paper presents the simulation of optically activated surface plasmon waves based on kretschmann configuration by using prism. 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. Other condensed matter}, year={2018} }. 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. 2 a schematic of the practical kretschmann spr sensor configuration. 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. A collimated gaussian beam is irradiated to the prism and the excited surface plasmons propagate along the sides. @article{vinogradov2018excitingsp, title={exciting surface plasmon polaritons in the kretschmann configuration by light beam.}, author={a. 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. Kretschmann configuration of spr gas sensing method. Comsol simulation of the formation of surface plasmon polaritons in the kretschmann configuration. The cone angle of the prism and the metallic film thickness are designed to match the excitation conditions for kretschmann configuration. In kretschmann configuration, metal thin film directly is deposited in the prism. Refractive index of the prism, respectively, and denotes the wavelength of incident light. Surface plasmon resonance (spr) is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light.

Sambles will clear all you doubts. The kretschmann configuration uses the metal film on a glass block, whatever shape it has. Figure 1 illustrates the kretschmann spr configuration used in our numerical simulation and experiment. This niche of spr sensing has been especially exploited in biological sciences for the determination of binding constants and the identification of binding partners. 1 kretschmann configuration in spr depicting the conversion of energy from light waves to surface plasmons via a gold/dielectric interface. This result a shift in the dispersion relation (because the glass has a refractive index more than 1), and gives a possible resonance angle. Kretschmann configuration is one among them.
