Is Lumerical RCWA capable of implementing anisotropic materials?

      Hello,

      I have been using Lumerical RCWA recently and it works really nice. I was wondering if we could use anisotropic materials with it. I attempted to use them but the results clearly took one of the axis dispersion curve and calculated accordingly. If it is possible to do this, could you briefly describe it?


      Thanks,

      Omer

      Thankyou for trying our new RCWA solver. Currently it is still under intense improvement and has no anisotropic capability. Please keep an eye on the release news which declares new features.

      Thank you so much gsun, I have one more question if that is okay. Can we implement substrates in the RCWA?

      Thanks Omer

      I believe so. You can try just a substrate and see if the result is ok. I have not used it yet.
