Wire Reference

This keyword is used in conjunction with the CAPACITANCE COMPUTE keyword. In the absence of the WIRE REFERENCE or the CYLINDRICL SHELL REFERENCE keyword, the default return ground for an exposed segment is assumed. The default return ground is a ground plane, at z = 0.0. With the WIRE REFERENCE keyword, a segment conductor can be designated as the ground return. The exposed segment plus the wire ground are assumed to be in free space as indicated by the choice of the second level keyword "WIRE IN FREE SPACE" which is required in the input file. A wire reference can only be defined when the SEGMENT/COMPLEX or the SEGMENT/COMPLEX2 keyword combination pairs are used to define the corresponding segment to which the wire reference is associated.

There are three second level keywords associated with the WIRE REFERENCE keyword. These are:

• WIRE IN FREE SPACE

• DIELECTRIC

• FILAMENT NUMBER
