Creating a Dielectric Medium (Debye Relaxation)

Create a frequency-dependent dielectric using the Debye relaxation method. Use the Debye model to describe the relaxation characteristics of gasses and fluids at microwave frequencies. It is derived for freely rotating spherical polar molecules in a predominantly non-polar background.

  1. On the Construct tab, in the Define group, click the  Media icon. From the drop-down list, click the  Dielectric icon.

    Figure 1. The Create Dielectric Medium dialog (Debye relaxation).
  2. In the Definition method field, from the drop-down list select Debye relaxation.
  3. In the Relative static permittivity field, enter a value for εs.
  4. In the Relative high frequency permittivity field, enter a value for ε.
  5. In the Relaxation frequency field, enter a value for fr.
  6. [Optional] Specify the magnetic properties of the dielectric.
  7. [Optional] In the Mass density (kg/m^3) field, enter a value for ρ.
  8. In the Label field, enter a unique label for the dielectric.
  9. Click Create to create the dielectric and to close the dialog.
