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.
