Creating a Dielectric Medium from a Frequency List
Define a frequency-dependent dielectric by specifying data points at a range of frequencies. The values for the dielectric properties are linearly interpolated to obtain the dielectric properties at frequency points other than specified.
-
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 (Frequency list).
- In the Definition method field, from the drop-down list select Frequency list (linear interpolation).
Specify if the frequency points are manually entered or imported from a
file.
-
Select one of the following:
- To enter each frequency point, click Dielectric loss tangent or Conductivity and enter the dielectric properties for each frequency point.
- To import the frequency points from a file, click Import
points.
- In the File name field, browse for the file you want to import.
- [Optional] In the Scale by
field, enter a value to scale the points.
For example, if you import a value of
2
, scale it by10e9
to change the value to 2 GHz. - Under Delimiter, click the delimiter type you use in your file.
- Click OK to close the Import Points dialog.
- [Optional] Specify the magnetic properties of the dielectric.
- [Optional] In the Mass density (kg/m^3) field, enter a value for ρ.
- In the Label field, enter a unique label for the dielectric.
- Click Create to create the dielectric and to close the dialog.
