We theoretically investigate light scattering from a bi-sphere system consisting of a gold nanosphere and a lossless dielectric microsphere illuminated at a resonant optical wavelength of the microsphere. Using generalized multisphere Mie theory, we find that a gold nanosphere 100 times smaller than the dielectric microsphere can be detected with a subdiffraction resolution as fine as one-third...

The powerlaw patterns in Mie scattering (the normalized light intensity IðhÞ=Ið0Þ vs. the dimensionless qR where q 1⁄4 4pk 1 sin h 2 is the magnitude of the wave vector transfer at the scattering angle h for wavelength k, and R is the radius of the nonabsorbing sphere with a relative refractive index m > 1) are analyzed using the geometrical optics approximation for particles of a large size pa...

This technical note extends previous Mie calculations to show that there are complex relationships between the asymmetry parameter g and the upscatter fractions for monodirectional incident radiation b(m0). Except for intermediate zenith angles and for the upscatter fraction for diffuse radiation, there are significant differences between b(m0) predicted by the Mie theory and that approximated ...

Under condition irrelevant scat...

A simple optical method based on absorption of monochromatic light to investigate the dynamics of single walled carbon nanotube SWCNT suspensions is described. The well dispersed suspensions display a complex behavior, exhibiting peaks due to resonant scattering from SWCNT bundles with increasing diameters as a function of time. The results indicate that the bundling of SWCNTs initiates almost ...

We provide the in-depth characterization of light-polymer nanowire interactions in the context of an effective Mie scattering regime associated with low refractive index materials. Properties of this regime sharply contrast with these of resonant Mie scattering, and involve the formation of strictly forward-scattered and coupling-free optical fields in the vicinity of core-shell polymer nanowir...

A laboratory experiment helps to understand the light scattering property of regolith like samples with known compositions and other physical parameters. The laboratory data so obtained can be compared with the existing in situ data on celestial objects like asteroids. Further, it may be analyzed with the help of various theoretical models to understand the light scattering processes from regol...

The transport properties of photons traveling through random media are of great fundamental and applied importance. For instance the dwell time due to resonant Mie scattering can lead to a significant reduction in transport velocity. Here, we have measured directly the energy-transport velocity of photons in strongly scattering media using a combination of time resolved transmission, measuring ...

Photoacoustic tomography (PAT) is an imaging technique combining strong contrast of optical imaging to high spatial resolution of ultrasound imaging. These strengths are achieved via photoacoustic effect, where a spatial absorption of light pulse is converted into a measurable propagating ultrasound wave. The method is seen as a potential tool for small animal imaging, pre-clinical investigatio...

Abstract. The scattering of an electromagnetic plane wave by a spherical particle was solved analytically by Gustav Mie in 1908. The Mie solution is expressed as a series with many terms thus obscuring the physical insight. The purpose of this paper is to show that when light scattering is described through the Ramsauer model, the physics gets simpler. For instance, the origin of the structures...
