We also investigate the forces on a dielectric bead in the vicinity of the antennas for different positions to show the optical force characteristics of the bowtie-shaped antennas. Finally, the force analysis on different bead radiuses demonstrates the trapping efficiency of our antenna system....

An atom placed in a focused laser beam will experience a dipole force due to the gradient in the interaction energy, which is analogous to the well-known optical tweezers effect. This force will be dependent on the velocity of the atom due to the Doppler effect, which could potentially be ...
Despite the incident light intensity is uniform over the xy plane, the scattering of light among the spheres modifies the spatial light distribution, as shown in b–e, which induces binding forces. The colored contour plots in b–e represent the normalized total field intensity for the spheres ...

Besides, forces that are not associated with any sort of the energy flow (e.g., the gradient force owing to the inhomogeneous intensity and the polarization-dependent dipole force emerging due to inhomogeneous polarization) can strongly modify the observed mechanical action. The polarization-dependent...
