The albedo and dichroic polarization of spheroidal particles are studied. For the description of the phase function two asymmetry parameters g|| and g⊥ characterizing the anisotropy in forward/backward and left/right directions are introduced and calculated. The consideration is based on the solution to the light scattering problem by the Separation of Variables Method (Voshchinnikov and Farafo...

The inherent optical properties (IOPs) of marine particles are most-often modeled and interpreted by assuming that they are homogeneous spheres. Although this approach has been fruitful, the next logical step in modeling the IOPs of marine particles is to abandon the normally-employed spherical approximation and use more realistic idealizations of their shape. The advent of computer codes capab...

Optical trap assisted nanopatterning is a laser direct-write technique that uses an optically trapped microsphere as a near-field objective. The type of feature that one can create with this technique depends on several factors, one of which is the shape of the microbead. In this paper, we examine how the geometry of the bead affects the focus of the light through a combination of experiments a...

To effectively estimate the influence of multiple scattering caused by haze particles on the misestimating of CO2 concentrations, it is necessary to understand the scattering properties of haze particles in the shortwave infrared (SWIR) wavelength range (~1.6μm) using satellite data. Due to the complexity of structures and components of haze particles, this paper investigates effects of particl...

Dielectric characterisation of polarisable particles, and prediction of the forces and torques exerted upon them, relies on the knowledge of the effective, induced dipole moment. In turn, through the mechanism of depolarisation, the induced dipole moment of a particle is strongly dependent upon its shape. Since realistic shapes create modelling difficulties, the ‘spherical particle’ approximati...

Through the molecular dynamics simulation method, we demonstrate that long semi-flexible polymer chains can serve as an effective soft elastic medium for manipulating the ordered structures of small numbers of building blocks, which can be easily controlled by the chain bending stiffness. For two spherical particles in a polymer-particle mixture, three types of local organization are identified...

Using the multiple scattering model of non-line-of-sight ultraviolet light to simulate and analyze atmospheric channel characteristics in complex environment haze dust. The Mie theory T matrix method are used path loss spherical particles non-spherical with particle concentration at different communication distances. results show that when distance is less than 50 meters, quality under severe b...

This paper presents detailed numerical calculations of the dielectrophoretic force in traps designed for single-cell trapping. A trap with eight planar electrodes is studied for spherical and ellipsoidal particles using the boundary element method (BEM). Multipolar approximations of orders one to three are compared with the full Maxwell stress tensor (MST) calculation of the electrical force on...
