Kretschmann Configuration. In kretschmann configuration, metal thin film directly is deposited in the prism. There are several configurations of spr devices that are capable of generating and measuring surface plasmon resonance (1). 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. I hope this paper by j. And then the thickness of metal is about 50 nm. 1 kretschmann configuration in spr depicting the conversion of energy from light waves to surface plasmons via a gold/dielectric interface. This paper presents the simulation of optically activated surface plasmon waves based on kretschmann configuration by using prism. Sambles will clear all you doubts. The refractive index dispersion effect of ito material led to resonances in the near infrared and visible wavelength regions. Surface plasmon resonance (spr) is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light. Kretschmann configuration is one among them. 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. The metal that usually used is silver, gold and aluminum. 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.

2 a schematic of the practical kretschmann spr sensor configuration. This is reasonably described in the raether book. 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. 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. 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. There are several configurations of spr devices that are capable of generating and measuring surface plasmon resonance (1). This niche of spr sensing has been especially exploited in biological sciences for the determination of binding constants and the identification of binding partners.
Simulated electric fields of the surface plasmon wave which appears at the interface between the metal thin film and dielectric layer are observed.
Comsol simulation of the formation of surface plasmon polaritons in the kretschmann configuration. Simulation of surface plasmon polaritons via kretschmann configuration. 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. The kretschmann configuration uses the metal film on a glass block, whatever shape it has. The refractive index dispersion effect of ito material led to resonances in the near infrared and visible wavelength regions. A collimated gaussian beam is irradiated to the prism and the excited surface plasmons propagate along the sides. This paper reviews four main branches of neuroplasmonics comprising prism coupler configurations, the combination of spr and fluorescence microscopy and methods based on nanorods and plasmonic crystals. This is reasonably described in the raether book. There are several configurations of spr devices that are capable of generating and measuring surface plasmon resonance (1).

And then the thickness of metal is about 50 nm. Kretschmann configuration of spr gas sensing method. 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. This paper presents the simulation of optically activated surface plasmon waves based on kretschmann configuration by using prism. This result a shift in the dispersion relation (because the glass has a refractive index more than 1), and gives a possible resonance angle. 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 kretschmann configuration, metal thin film directly is deposited in the prism. A prism is normally used to match the wave vectors between surface plasmons and the incident light. Excitation by atr kretschmann configuration otto configuration. 2 a schematic of the practical kretschmann spr sensor configuration. Figure 1 illustrates the kretschmann spr configuration used in our numerical simulation and experiment. 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. 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. The metal that usually used is silver, gold and aluminum. Simulated electric fields of the surface plasmon wave which appears at the interface between the metal thin film and dielectric layer are observed. The cone angle of the prism and the metallic film thickness are designed to match the excitation conditions for kretschmann configuration. 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. 1 kretschmann configuration in spr depicting the conversion of energy from light waves to surface plasmons via a gold/dielectric interface.
