Tuning the resonance frequency of Ag-coated dielectric tips.
A finite element model was built to investigate how to optimize localized plasmon resonances of an Ag-coated dielectric tip for tip-enhanced Raman spectroscopy (TERS). The relation between the resonance frequency, the electric field enhancement and the optical constant of the dielectric tip was numerically investigated. The results show that increasing the refractive index of the dielectric tip...
متن کاملTheory and practical considerations of multilayer dielectric thin-film stacks in Ag-coated hollow waveguides.
This analysis explores the theory and design of dielectric multilayer reflection-enhancing thin film stacks based on high and low refractive index alternating layers of cadmium sulfide (CdS) and lead sulfide (PbS) on silver (Ag)-coated hollow glass waveguides (HGWs) for low loss transmission at midinfrared wavelengths. The fundamentals for determining propagation losses in such multilayer thin-...
متن کاملThe Ag dielectric function in plasmonic metamaterials.
Ag permittivity (dielectric function) in coupled strips is different from bulk and has been studied for strips of various dimensions and surface roughness. Arrays of such paired strips exhibit the properties of metamagnetics. The surface roughness does not affect the Ag dielectric function, although it does increase the loss at the plasmon resonances of the coupled strips. The size effect in th...
متن کاملChange in Dielectric Properties in the Microwave Frequency Region of Polypyrrole–Coated Textiles during Aging
Complex permittivity of conducting polypyrrole (PPy)-coated Nylon-Lycra textiles is measured using a free space transmission measurement technique over the frequency range of 1-18 GHz. The aging of microwave dielectric properties and reflection, transmission and absorption for a period of 18 months is demonstrated. PPy-coated fabrics are shown to be lossy over the full frequency range. The leve...
متن کاملOn the Cold Emission Mechanism of Diamond Coated Tips
A formal implementation of the Fowler-Nodheim equation to emission characteristics of diamond coated cold cathodes gives values of the work function which depend on surface curvature of the coating, thus making it incorrect. Experiments with diamond coated Si tips having different coating radii have shown, that their emissivity depends on the radius of the Si tip rather than on the radius of th...
