Hi There, My first experience with Lumerical! I appreciate your help in these…

1)when we define a material ourselves, with n and k, to show that the

material is lossy shall I take k a positive number or negative number?

- how can I calculate the field, field gradient, and probably any other

function of the field values calculate by Lumerical at certain point in

space within the software.

3)I am attaching this file where I am trying to calculate the optical

force on the particle and also need the field and field gradient

components at the center of the particle.

… Well just don’t see where I can attach my files.But hopefully you can help me with that.

Thanks,

FV
