  Hii,
  
  I want to add these material properties in hfss. I have enables the beta option to add these value but it is not updating the result while using this material in model solution.
  
  Is this only for transient solver? and if yes so how I can analyze the periodic boundry condition through this drude input.
  
  This is the attached reference paper:
  
  Active thermally tunable and highly sensitive terahertz smart windows based on the combination of a metamaterial and phase change material.
  
  Pls. suggest how to implement in hfss frequency domain.

  If you are referring to the "HFSS Nonlinear Drude for Implicit Transient" beta option, please note that it can only be used for transient analysis.
  
  Additionally, periodic boundary conditions cannot be used in transient analysis.

  So how I can implement in frequency domain?
