Frequency dependent material properties

• In material properties, you can set frequency dependent material properties as highlighted.
• There are multiple options for frequency dependent material setup

Option 1: Piecewise linear input

• Enter the values in the pop-up window for the following parameters
  • Frequency Range
  • Relative Permitivity
  • Relative Permeability
  • Dielectric loss tangent
  • Magnetic loss tangent
• Click OK after finish

• Then, the pwl function will be automatically entered in the material properties

Option 2: Enter Frequency Dependent Data Points

• Click Edit to enter the data points and give the dataset a name.
• Alternative method to create the project dataset is
  • Go to Project à dataset and create a new dataset
• Click OK after done.
• Using ‘$’ prefix to indicate the data to be a project dataset

• The pwl function will be automatically created in the material properties.
• If you create a project dataset using the alternative method, you can type the pwl function in the following format
• Pwl($dataset, Freq)
