WebSection 3 is dedicated to the guiding of particles with optical forces in continu- ous bulk media using different beam configurations, including Gaussian beams, propagation-invariant Bessel... WebApr 10, 2024 · Tractor beams, being able to produce optical pulling forces (OPFs) on particles, are attracted increasing attention. In this paper, non-paraxial Bessel tractor beams were generated by using polarization-insensitive metasurfaces. The OPFs were found exerted on the dielectric particles with specific radii at the axes of the beams.
