“…A group of spheres can be treated using the multiple Mie scattering theory [37,38]. Except spherical objects, spheroidal or cylindrical ones are also often considered theoretically [39][40][41]. Optical forces acting on particles with more complex shapes must be calculated using numerical approaches -for example, coupled dipole method [42,43], finite element method [44], or finitedifference time-domain method [45][46][47][48].…”

Light at work: The use of optical forces for particle manipulation, sorting, and analysis

We review the combinations of optical micro-manipulation with other techniques and their classical and emerging applications to non-contact optical separation and sorting of micro- and nanoparticle suspensions, compositional and structural analysis of specimens, and quantification of force interactions at the microscopic scale. The review aims at inspiring researchers, especially those working outside the optical micro-manipulation field, to find new and interesting applications of these methods.

“…A group of spheres can be treated using the multiple Mie scattering theory ͑Xu, 1995; . In addition to spherical objects, spheroidal or cylindrical ones are also often considered theoretically ͑Nieminen et al, Grzegorczyk et al, 2006c;Nieminen, Kröner, et al, 2007;Xu et al, 2007͒. Optical forces acting on particles with more complex shapes must be calculated using numerical schemes; for example, the coupled dipole method ͑CDM͒ ͑Hoekstra . If the object is much larger than the trapping light wavelength, the ray-optics model can be used ͑Ashkin, 1992; Gussgard et al, 1992;Gu et al, 1997;Mazolli et al, 2003͒. The second approach derives the optical force from the Lorentz force acting on both currents J due to the polarization of dielectric and bound charges e at the boundaries ͑Mansuripur, , 2005Kemp et al, 2005, ͗F͘ = 1 2 Re ͭ͵ ͗ e E * + J ϫ B * ͘dV ͮ .…”

Colloquium: Gripped by light: Optical binding

͑Published 3 June 2010͒The light-matter interaction has been at the heart of major advances from the atomic scale right to the microscopic scale over the past four decades. Confinement by light, embodied by the area of optical trapping, has had a major influence across all of the natural sciences. However, an emergent and powerful topic within this field that has steadily merged but not gained much recognition is optical binding: the importance of exploring the optically mediated interaction between assembled objects that can cause attractive and repulsive forces and dramatically influence the way they assemble and organize themselves. This offers routes for colloidal self-assembly, crystallization, and organization of templates for biological and colloidal sciences. In this Colloquium, this emergent area is reviewed looking at the pioneering experiments in the field and the various theoretical approaches that aim to describe this behavior. The latest experimental studies in the field are reviewed and theoretical approaches are now beginning to converge to describe the binding behavior seen. Recent links between optical binding and nonlinearity are explored as well as future themes and challenges.

“…The generalized Lorenz-Mie theory (GLMT) developed by Gouesbet et al is effective to describe the electromagnetic scattering of a shaped beam by a spherical particle [8][9][10][11], and has been extended by Han et al to the case of a spheroidal particle at axial incidence [12,13]. Xu et al investigated the general case of an arbitrarily oriented, located, and shaped beam scattered by a homogeneous spheroid [14], and have applied it to the radiation pressure force (RPF) calculation for spheroidal particles [15].…”

An analytic solution to the scattering by a coated spheroidal particle, for arbitrary incidence of a Gaussian beam, is constructed by expanding the incident and scattered electromagnetic fields in terms of spheroidal vector wave functions. The unknown expansion coefficients are determined by a system of linear equations derived from the appropriate boundary conditions. Numerical results of the normalized differential scattering cross section of the conducting and coated spheroidal particle are evaluated, and the scattering characteristics are discussed concisely.
