Reply To: Metasurface FDTD:reflectivity and transmittance is greater than 1 and big noise

Thank you for reply.

I use your method but it doesn't change result. Reflection and transmission is over 1 and it have big noise yet.
Is normalization necessary in this simulation? It it is, how to normalize reflection and transmission?
Or if you have another method, could you tell me?

Thank you.
