Adding a PEC Ground Plane

A perfectly electric conducting (PEC) ground plane, parallel to the xy-plane, can be added to the model using the following procedure:

1. Navigate to the Setup tab > Environment panel.
2. Select the Perfect option in the Ground Plane box (see Fig. 1).
3. Set the ground plane position under the Position label (Z-coordinate).

When the Perfect ground is selected, an infinite PEC ground plane will be placed at the specified Z-coordinate relative to the xy-plane:

• If Z > 0, the PEC ground plane will be above the xy-plane.
• If Z = 0, the PEC ground plane will be on the xy-plane.
• If Z < 0, the PEC ground plane will be below the xy-plane.

The ground plane is represented as a square with cross diagonals to visualize its position (see Fig. 2). Note that this is only a symbolic representation, as the ground plane itself is infinite in extent.
