Three-dimensional analysis of silver nano-particles doping effects on super resolution near-field structure

Three-Dimensional Analysis of Scattering Field Interactions and Surface Plasmon Resonance in Coupled Silver Nanospheres

“…Such enhancements play an important role in surfaceenhanced Raman scattering (SERS) [1]. Recently, several works have attracted considerable interest as an alternative to conventional optics in manipulating the properties of light and applications, such as subwavelength optics nanophotonics [2], magneto-optic data storage [3], chemical and biological sensors [4], super-resolution near-field structure [5,6], waveguides for propagating light in nanoscale structures [7], and acting as a key role in the amplification of the Raman signal of molecules adsorbed on metal particles [8].…”

“…Special attention on this range is based on three reasons, i.e., the analytic solution that the field enhancement at resonance is maximized for spherical particles with diameters in this range, the experimentally observed enhancement in SERS is the largest for nanoparticle dimensions of this scale, and the technology is now reaching the state where particles of this size can be produced in a controlled manner. If such a spatial distribution of materials within 3D Ag nanosphere models that produces the desired results are able to find, it would enable us to model the Super-RENS [5,6] writing and reading process and to better understand the Super-RENS phenomenon. In addition, by manipulating the localized SPR, local field enhancement, and near-field coupling of nanoparticles, it is promising to be able to focus, to transport, and to interact with light in nanoscale region and are being explored for various applications in chemical and biological sensors [15], nano-photonic devices [16], plasmonics [17,18], etc.…”

Surface Plasmon Effects Excited by the Dielectric Hole in a Silver-Shell Nanospherical Pair

“…With a simple solid silver nanocylinder, strong light absorbing and scattering occur at the plasmon resonance frequency and high local fields are excited around the nanoparticle [26]. However, in a system that consists of a solid silver or a silver-shell nanospherical pair, the surface plasmon broadens and the resonant condition is modified for particle-particle interaction.…”

Long-ranging propagation based on resonant coupling effects using a series connection of ten nanoshells in a plasmon waveguide

“…Surface plasmons concentrate and locally enhance light intensity. This property stimulates investigations on nanoscale plasmonic devices because of their possible applications in near-field optics, sensing, and data storage [1][2][3][4]. Plasmon waveguides may be useful in the construction of optical metamaterials that exhibit novel optical properties because of their subwavelength structure.…”
