How to slove the radiation forces on a particle?

Please login with a confirmed email address before reporting spam

I want to slove the radiation forces (the gradient force and the sacttering/absorptive forces) by a tightly focus laser beam on a dielectric/metallic particle.
Can anyone tell me which model is appropriate and how can i import the focused optical field?
