  Hi all,
  I am recently working on non linear scattering simulations from a single scatterer. I need to make the polarizabilty/refractive index as a function of incident electric field. Is there any provision to do so in FDTD. Please let me know.

  If the nonlinearity falls into the Lumerical models: https://optics.ansys.com/hc/en-us/articles/360034394734
  you can simulate them directly. Otherwise it can be challenge.
