IEMI analysis of critical infrastructures by simulations using a multi-method coupling strategy

Numerical simulations of scenarios with intentional electromagnetic interference (IEMI) attacks against critical infrastructures (CIs), like power plants or financial centers, require the consideration of very large solution space compared to the wavelength. Different electromagnetic wave propagation paths from the adversary source to the susceptible electronic target have to be taken into account. The distance can be up to hundreds of meters and several coupling mechanisms and physical effects can occur in the frequency band of interest. Today, no numerical method exists to treat such kind of large IEMI scenarios in a single simulation step. The electromagnetic topology (EMT) scheme of the scenario is important to create equivalent models and to develop a coupling strategy for suitable methods. Here, a generic course of action for a comprehensive IEMI scenario simulation is provided reaching from EM topology to computational analysis via equivalent models and simulation code coupling chains.
