The two controlling parameters for the onset of levitation and for the dynamics of the levitating microparticles are the size of the particle and the incidence angle of solar photons. For particles of 0.1 μm, levitation can occur if the solar incidence angle is larger than 76.2°. The role of solar pressure forces in the horizontal motion of ...

A novel method of levitation, using an actively controlled electric field, launches, captures, and stably suspends a microscopic (∼15 μm) particle in high vacuum. While held to within one diameter in the vertical direction, the particle is allowed to oscillate nearly freely in the horizontal plane under the influence of a central restoring force.
