Adding a Real Ground Plane

A real (imperfect) ground plane, located on the xy-plane (Z = 0), can be added to the model using the following procedure:

1. Navigate to the Setup tab > Environment panel.
2. Select the Real option in the Ground Plane box (see Fig. 1).
3. Specify the Real Ground Option:
   • Sommerfeld-Wait/Asymptotic
   • Reflection Coefficients/Asymptotic
   • Radial Wire Ground Screen
4. Set the ground Permittivity and Conductivity. If a Radial Wire Ground Screen is selected, also specify the radial length, number of radials, and wire radius.

The ground plane is represented as a square with cross diagonals to indicate its position (see Fig. 2). Note that this is only a symbolic representation, as the ground plane itself is infinite in extent. When a Radial Wire Ground Screen is selected, the radial wires lying on the ground will be displayed instead of the ground plane symbol (see Fig. 3).
