Shreyas, Both RF and Wave Optics physics interfaces can be used to solve this problem. There are several papers from Comsol conferences about surface plasmon resonance for both Kretschmann-Raether and Otto configurations – try to search keywords “surface plasmon resonance”. From the plasmon band shift versus the refractive index, ultra-high local surface plasmon resonance sensitivity (413 nm RIU −1 or 1.24 eV RIU −1, figure of merit (FOM) = 4.59) was reached at ∼630 nm, making these materials promising for chemical/biological sensing applications. AbstractLocalized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments.Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. The local surface plasmon resonance effect induced by metal nanoparticles on perovskites provides a powerful approach to enhance the photoluminescence of such all-inorganic systems.

In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microscopy (CLEM) tag for biological samples. Gold NPs in ultra-thin sections for TEM revealed that LSPR could be observed by optical microscopy at sizes of 20 nm or larger.

The extinction, absorption, and scattering efficiencies band of two, three, and more silver nanospheres clusters are discussed in detail. The clusters show new types of the local surface plasmon resonances compared with single silver nanosphere. Our results The resonance frequency of the oscillation, i.e., the surface plasmon (SP) energy, it is essentially determined by the dielectric properties of the metal and the surrounding medium, and by the particle size and shape. The collective charge oscillation causes a large resonant enhancement of the local field inside aand near the NP.
