  Hello, is it possible to define anisotropic optical materials in FEEM?
  
  Thank You

  Hello
  yes the FEEM solver supports spatially varying isotropic and diagonally anisotropic materials. You have to create a (.mat) file with unstructured dataset. Then import it with importdataset script command can also be used to import spatially varying index data into nk import object.. Please have a look at the following links:
  nk-material-finite-element-Simulation-object
  Spatial-n-k-data-Simulation-object
  Graded-index-fiber-with-FEEM
  The following link is for FTDD and MODE that use rectilinear mesh, but you can have a look and get some information from them.

  I hope I helped.
