Creating a Waveguide Port (Mesh)

Apply a waveguide port to a mesh face.

  1. On the Source/Load tab, in the Ports group, click the  Waveguide port icon.

    Figure 1. The Create waveguide port (mesh) dialog.
  2. Click the Specification tab.
  3. In the Face field, use point entry to specify the face using one of the following workflows:
    • In the 3D view, click on the relevant face.
    • In the details tree, click on the relevant face.
    A propagation direction and reference direction are automatically defined.

If the propagation direction is not correct, you can change the direction.

  1. [Optional] Clear the Propagation direction opposite to normal check box to change the propagation direction to be in the same direction as the normal.

If the reference vector is not correct, you can specify the reference vector.

  1. [Optional] Under Reference vector, specify the reference vector.
  2. [Optional] If the polarity of the port is to be reversed, select the Reverse polarity check box.
  3. In the Label field, add a unique label for the waveguide port.
  4. Click the Advanced tab.

When the number of modes to be considered is not specified, Feko calculates the number automatically.

  1. [Optional] To specify the number of modes, click the Manually set the maximum modal expansion indices check box.
  2. Click Create to create the wire port and to close the dialog.
