As I understood, you are trying to define a refractive index varying with space which is feasible in principle. You can learn from https://optics.ansys.com/hc/en-us/articles/360034901993-Spatial-n-k-data-Simulation-object

Thanks to enquirer and responder. Was looking forward to a very similarproblem.

Many thanks to both responders, I succeeded to create the spatial n,k profile in Lumerical mode, is the Lumerical FEEM more adequate for the task of modes calculations with a spatial n, k profile?
