6       I/O Ports

The I/O ports, Mesh Snapping Planes, Absorbing Boundary Conditions and NTF can be introduced in a manual way (see Manual Drawing chapter for more information).

We suggest more convenient way of introducing the following I/O ports using a set of dedicated dialogues:

• Point Source or Probe using Point/Probe dialogue

• Transmission Line Port using Transmission Line Port dialogue

• Absorbing Boundary Conditions using ABC Wall or ABC Box dialogue

• Lumped Impedance using Lumped Impedance dialogue

• NTF box using NTF dialogue

• Plane Wave box using Plane Wave dialogue

• Mesh Snapping Planes, Symmetry Planes or Boundaries using Snapping Plane dialogue

• Fields Monitor box using Fields Monitor dialogue

An alternative way of introducing the I/O ports is using special UDOs available in the UDO library.
