hi, I am calculating trapping potential by optical trapping integral. In my model, the focused light is incident into sharp gold substrate, thus the huge enhanced electric field causes the optical trapping something. I already get the optical trapping force, however, I cannot solve the trapping potential by the optical trapping force.

In detail,

As I searched in searching engine like google, the optical trapping potential is calculated by the integral equation as attached below, however, I cannot apply the equation in COMSOL. What can I do? Somebody helps me, please.



as I mentioned before, I already have the force (Fx, Fy, Fz, respectively)

Thanks,
