  hi
  i want to define a magneto-optic material in lumerical. i have seen the guidelines in lumerical website and i can define a material biased in cartesian coordinates. now i want to define a material biased in phi direction in cylinderical coordinates. how can i do that?

  In such case you will need to import the space variant refractive index: https://optics.ansys.com/hc/en-us/articles/360034901993-Spatial-n-k-data-Simulation-object

  hi
  thank you dear Guilin for your answer. i imported my desired space variant refractive index but i want to define this space as a material and i use it in my structure. i dont know how can i do that. i want to use this material as a cylinderical layers in my structure.

  Sorry I missed your further question.
  If the material property changes in space you will need to use spatial index import: https://optics.ansys.com/hc/en-us/articles/360034901993-Spatial-n-k-data-Simulation-object
  
  You will need to create the data and save it in txt file.
