"Optical forces are generally calculated only on spherical dielectric objects placed into a laser beam. It has been already demonstrated that a standing wave offers several useful advantages comparing to a single beam trapping. Firstly it can confine objects with higher refractive index and secondly it provides higher optical forces acting on spheres of certain sizes. Therefore we focus here on the problem how to modify the object shape so that the axial optical force is enlarged even more. We consider an object composed of overlapping spheres in linear chain and look for maximal optical force. We demonstrate that by suitable changing such object geometry the final optical force can exceed by an order of magnitude in comparison to the optical force acting on a single sphere." . "3"^^ . .
