Cable Reference and Ground

MHARNESS® is a transmission line code, and therefore, requires a reference for implementation. The reference is always associated with exposed segments. If the impedance matrices are manually defined, then the reference is implicit within the entries of the matrices. However, for automatic computation, the reference must be identified. In MHARNESS the reference is always assumed to be a ground plane (default condition) unless otherwise specified. The ground plane can be perfectly conducting (PEC) or lossy. A PEC ground is the default condition. A wire reference and a cylindrical ground reference may also be specified.

The ‘Section 11: Cable Reference / Ground’ section of the input file contains three possible first level keywords. These keywords are listed and described below in order of appearance in the list.

1) WIRE REFERENCE

2) CYLINDRICAL SHELL REFERENCE

3) REFERENCE RESISTANCE
