Hi, i created two model one with sampled data of permittivity and one with drude material. But in there reflection spectrum of drude model is not smooth. My input are permittivity, plasma  and collision frequency

Thank

Hello, 

could you please share a little bit more information regarding your model? For example screenshot of your design would be helpful. What is the reflectance for the perimitivity material model and would you expect from your design? 

Also I would suggest to refer to the folloiwng link to get more information regarding the Drude model:

I hope I helped. PLease reach out to me in case you need further information. 

Kind regards
