Abstract
The self-arrangement of several micron-sized particles (due to their mutual scattering of light fields) is called optical binding. The scattered light is induced by incident laser fields which may be also used for partial localization (similarly to optical tweezers) of the particles in the water solution. We have previously experimentally studied the optical binding in the configurations employing two counter-propagation Bessel beams and these results were sufficiently supported by our numerical simulations (Coupled dipole method { CDM). Here we present numerical studies of configurations where some symmetries of the problem are broken. We study how the difference of sizes of two spherical particles influences their spatial stable separation. These results may serve for detection of particles of different composition, size or shape.
