Abstract
For the control of electromagnetic interference a topological approach is strongly recommended. It allows for a complex system to be structured into a feasible number of zones, each having certain levels of energy density, transient amplitudes, background noise, etc. Electromagnetic compatibility (EMC) is reached by making sure that all system elements comply with those levels. In this paper, a simulation program is described that facilitates the EMC specification. The user interface forces the user to adapt to the topological approach. Sources, zone properties, cables, and other coupling path etc., are specified and disturbances in arbitrary locations are computed. By comparing computed results for varying system properties with known emission and immunity properties of system elements, different ways to reach EMC can be evaluated. Including actual external threats among the sources, EMC compliance means that the system is immune to intentional electromagnetic interference, high-power electromagnetics, electromagnetic pulse, lightning, etc.
