Validity of Equivalent Source Representation for Coaxially Shielded Cables and Multiconductor Cables

摘要

Efficient equivalent source representations were developed for coaxially shielded cables and for multiconductor cables. The correctness of these equivalent source representations was validated for linear and nonlinear terminations. The distribution of shield coupling parameters was studied for shielded multiconductor cables. The results of this study indicate that an approximate equivalent source excitation may be used for multiconductor cables, thereby reducing the source requirements even further. The approximate equivalent source excitation requires only two independent sources to represent the EMP response of the cable. The simplicity of the equivalent source excitation means that numerical models will run quicker, and system-level stimulation is possible with a lower power level and less complex simulators.
