EMC Modelling

The MBDA EMC modelling capability has been designed to accommodate all the specialist needs of delivering an advanced EMC modelling capability. It includes:

  • Finite difference electromagnetic penetration of enclosures and coupling into cables etc (ASERIS code)
  • Methodology for establishing critical paths of ingress to systems of electromagnetic radiation (MESAF 2.0)
  • CAD applications (based on IronCAD) for generating simple CAD models for ASERIS submission and for adapting complex project CAD models for evaluation in the ASERIS-MESAF system of codes

The MBDA EMC modelling capability has been implemented on dedicated high performance PC workstations for optimal speed and efficiency.


ASERIS-FD is a finite difference EMC modelling code, which has been adapted for the specification of slots and apertures. Since these frequently turn out to be the dominant points of ingress or egress for electromagnetic energy, efficient and accurate modelling treatment of slots and apertures can yield great benefits to customers.


Almost all real systems are too complex to be modelled accurately and comprehensively at all relevant levels of detail using finite difference type codes. In practice, it is necessary to reduce the complexity in any single ASERIS model, because the mesh size of a model is constrained by available computer power. Especially at high frequency the dominant routes of ingress/egress will often have dimensions which are below the mesh size and the routes will pass through several sub-elements of the system (e.g. outer casing, cables, electronics units etc). MESAF circumvents these spatially related issued by ignoring the spatial configuration of the system and instead treating it as an assemblage of nodes with a network of pathways for the transport of electromagnetic energy between them.
