Abstract

Electromagnetic topology based simulations have been performed for external field penetration and propagation through cables in adjacent semi-shielded and shielded systems. Following penetration through an aperture, the external pulse interacts with cables as distributed source elements. The interaction transfer function for the topological network was generated by assuming a short-circuited radiating dipole at the aperture. The simulation and analysis were performed using an electromagnetic topology domain computer code that analyzes multi-conductor transmission lines. Results show that the effects on cables depend on the nature of the external pulse and also on the amplitude and frequency component of the interacting pulse. In all cases of studies involving cross-talk geometry considerations the cables were terminated with 50 Ω. Other terminations are expected to produce different results.
