in this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. first, integral equationsgoverning unknown fields on the surface is obtained based on stratton-cho surface integral equations. then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. it is shown that in scatter...

Plasmonics, which are based on the collective oscillation of electrons due to light excitation, involve strongly enhanced local electric fields and thus have potential applications in nonlinear optics, which requires extraordinary optical intensity. One of the most studied nonlinearities in plasmonics is nonlinear absorption, including saturation and reverse saturation behaviors. Although scatt...

In this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic Ionic Liquids (ILs), 1 – allyl - 3 - methylimidazolium chloride ([Amim]Cl), 1 - ethyl - 3 - methylimidazolium chloride ([Emim]Cl), 1 - butyl - 3 - methylimidazolium chloride ([Bmim]Cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([Bmim]BF4) were investigated using conductivity and laser ...

the use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. this review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

Frequency up-scattered light produced by laser-plasma interaction was measured under three different plasma conditions. The corresponding down-scattered light was also observed. The measured wavelengths were, in all cases, in good agreement with the results of the enhanced Thomson scattcxing (ETS) theory. The upscattered band, shifted to a frequency higher than the laser frtquency wg, had not p...

The composition and existing species of the reaction production of Hg and X (X= Cl, Br and I) under different conditions, and their absorption, Rayleigh scattering (RS) and resonance Rayleigh scattering (RRS) spectra have been studied. The results show that the products exist in the form of nanoparticles as [HgX2]n aggregates under suitable conditions, and their average diameters increase with ...

In recent years, there is a lot of interest in synthesis of nanostructures as carriers for drug delivery.These structures are considered as a highly effective drug delivery system due to controlling drugrelease, protecting the pharmaceutical molecule, and environmentally friendly. In this study, thesynthesis of chitosan nanoparticles was carried out by chemical method. The nan...

We study the stability of the reconstruction of the scattering and absorption coefficients in a stationary linear transport equation from knowledge of the full albedo operator in dimension n ≥ 3. The albedo operator is defined as the mapping from the incoming boundary conditions to the outgoing transport solution at the boundary of a compact and convex domain. The uniqueness of the reconstructi...
