Abstract :
We analyzed the radiation force of a spherical particle near a substrate, When a particle near a substrate is illuminated with laser light, the radiation force was determined by the multiscattering between the particle and the substrate. We developed an analysis method including the multiscattering. The comparison of radiation force with and without the substrate is presented.
