specifies the tangential component of the electric field. It should in general not be used to excite a model. Consider using the Port or
Scattering Boundary Condition instead. It is provided mainly for completeness and for advanced users who can recognize the special modeling situations when it is appropriate to use. The commonly used special case of zero tangential electric field is described in the
Perfect Electric Conductor section.
