A methodology for modeling IEMI problems on complex scenarios

The Intentional Electromagnetic Interference (IEMI) threat to critical infrastructure containing electronic systems presents a formidable compendium of problems. In this paper the IDS (Ingegneria Dei Sistemi1) modeling approach to the IEMI problem is described. The aim is to present a working philosophy to effectively address the IEMI issues. The approach is based on the following key tenets: a) a topological approach, b) a scaled working policy, c) multi-method tools (i.e. combining simple, asymptotic, full-wave, statistical and hybrid methods), d) “high-fidelity” modeling of multi-scale structures, and e) special models for solving particularly complex problems (e.g. field penetration into oversized shelters and field-to-cable coupling in electrically large but reverberating enclosures). Specific results relevant to high-fidelity modeling of real-life multi-scale structures, obtained through a special implementation of a “Multi-Level Fast Multipole Method Multi Resolution” (MLFMA-MR) code will be presented. A significant part of the content of this contribution is related to the activities performed in the frame of the European Union FP7 program “STRUCTURE” (http://www.structures-project.eu/), relevant to the theme “Critical Infrastructure (CI) Protection against Intentional Electromagnetic threats (IEMI)”. “STRUCTURES” program which will be also summarized in the following, together with a review of IEMI.
