We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Thank you. I have follow-up questions. 

  1. Is it possible to estimate how long the simulation will run in RCWA? FDTD gives such an estimation at the beginning of the simulation. What about RCWA?
  2. Is it theoretically possible that the RCWA and FDTD simulations never converge in certain situations?
  3. I observe that the RCWA simulation crushes for k values above 1800. What are the highest k values you have ever used in your simulations? Have you also observed the "crushing behavior"?

Thank you!
