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.
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 by
“10e9” 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.
