Creating an Impedance Sheet

Define a frequency-dependent impedance sheet. Apply the impedance sheet to wires or faces bordering free space or a dielectric region.

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

    Figure 1. The Create Impedance Sheet dialog.
  2. In the Definition method field, from the drop-down list select Frequency independent.
  3. In the Real part field, enter a value for the real part of the impedance sheet.
  4. In the Imaginary field, enter a value for the imaginary part of the impedance sheet.

Specify the frequency points manually or import them from a file.

  1. Select one of the following:
    • To import the frequency points from a file, click Import points.
      1. In the File name field, browse for the file you want to import.
      2. [Optional] In the Scale by field, enter a value to scale the points.
      3. Under Delimiter, click the delimiter type you use in your file.
      4. Click OK to close the Import Points dialog.
  2. In the Label field, enter a unique label for the impedance sheet.
  3. Click Create to create the impedance sheet and to close the dialog.
