I am trying to use RCWA in lumerial to do some simulations. However, I met some problems.<\/p>\n

    \n
  1. When I try to enable the option of USE TANGENT VECTOR FIELD or the option of report  ANGENT VECTOR FIELD in the the example of Photonic Crystal Slab (RCWA), the program will exit automatically.<\/li>\n
  2. <\/li>\n
  3. If this does not work, how to do the simulation for a system with metal? The number of K vectors will be huge.<\/li>\n
  4. if I have a light source with a specific polarization. how can I use the RCWA method to set the polarization? The incident angle should be easy to set, but RCWA always considers s or p polarization.<\/li>\n<\/ol>\n
