Optical tweezers, tools based on strongly focused light, enable optical trapping,
manipulation, and characterisation of a wide range of microscopic and nanoscopic …

The optical forces generated by a right-handed plasmonic Archimedean spiral (PAS) have
been mapped and analyzed. By changing the handedness of the circularly polarized …

Reflection and refraction of light can be used to trap small dielectric particles in the
geometrical optics regime. Absorption of light is usually neglected in theoretical calculations …
