faces bordering free space or a dielectric region.
-
On the Construct tab, in the Define group, click the Media icon. From the drop-down list, select the Impedance sheet icon.
-
In the Definition method field, from the drop-down list select Frequency
independent.
-
In the Real part field, enter a value for the real part
of the impedance sheet.
-
In the Imaginary field, enter a value for the imaginary
part of the impedance sheet.
Specify if the frequency points are manually entered or imported from a
file.
-
Select one of the following:
- To import the frequency points from a file, click Import
points.
- In the Filename field, browse
for the file you want to import.
- [Optional] In the Scale by
field, enter a value to scale the points.
- Under Delimiter, click the
delimiter type you use in your file.
- Click OK to close the
Import points dialog.
-
In the Label field, enter a unique label for the
impedance sheet.
-
Click Create to create the impedance sheet and
