By controlling interference of Mie resonance modes various nanostructures, we can achieve a large number nontrivial effects in nanophotonics.In this work, propose cylindrical structure which the spectral overlap Mie-type be controlled by drilling hole parallel to axis, thus changing unidirectional scattering.We further demonstrate that scattering patterns tailored rotating almost arbitrary scattered wave direction.

A study on refractive index sensing using a silver nanotube is carried out to investigate the relative advantages of gaseous and liquid samples outside tube (outer sensing) inside core (inner sensing). The geometrical material parameters are varied explore favorable performances covering range indices between 1.1 1.5. It shown that at three points considered consistently improved with decreased shell thickness radius in both modes. While performance also monotonously drastically enhanced...

Gold nanoparticles (AuNP) has been used in a wide range of applications especially medicine and optoelectronic due to its localized surface plasmon resonance (LSPR) effect. LSPR observation AuNP solution shows that the plasmonic peak absorbance spectra lies visible light around 520 nm with deep red-wine color. The optical characteristic is controlled by size shape including functionalization. Our research focused on adsorption study 3-mercaptopropionate (3-MP) (AuMP) synthesized ligand...

The development of a transflective display is important for reducing the energy consumption an outdoor display-device. Currently, it desirable to have transflector which can be switched between its reflective and transparent states. present work provides novel yet simple route such based on one-dimensional (1D) meta-lattice systems. system studied shown capable exciting tunable narrow resonance in reflectance spectra through generation scattered-field-induced polarizing-field system....

We report the results of a study using classical Mie theory and available experimental data Johnson Christy [Phys. Rev.

It is shown that spectral changes separately induced by varied core radius (R in ) axial offset (d) are consistent those reported for gold spherical nanoshell calculated celebrated plasmon hybridization model, including symmetry...

We report the study of light polarization property upon scattering off a dielectric nanorod in which direction incident is at an angle with respect to cylinder main axis. The numerical work done on basis cylindrical Mie theory. It shown that for different polarization, resulted cross-section spectra will also show characteristics varying angles. For TE case, resonance splitting observed due excitation new mode, while TM merging observed. An interference effect between modes variation then...

Abstract Localized Surface Plasmon (LSPR) occurs on the interface of Metal Nano Particle (MNP) when illuminated with electromagnetic wave, at a specific energy (wavelength). In this work, we model gold nanoparticle (AuNP) composite by its atomic polarizability, that is related to absorption, and dependence temperature. To compare resulted LSPR frequency shift AuNP system heated, synthesized MNP polymer (oleylamine) capped (AuOA) measured optical properties which resonance through...

We report a study on the reflective performance of dielectric meta-lattice formed by one-dimensional periodic arrangement silicon nanotubes. It was found that switching from transparent state to can be done simply varying one optical parameter meta-lattice. The shown capable providing near-zero and near-unity reflectance at any desired wavelength, even in oblique incidence cases. results are thus very promising for development future devices.
