Abstract:
Early-stage characterization of shielding effectiveness (SE) is essential for ensuring system-level
electromagnetic integrity. In this presentation we discuss the simulation of shielding effectiveness
(SE) from three different perspectives:
Solver Validation: A benchmarking of numerical simulation results against analytical equations to
quantify accuracy and point out differences in the computation methods.
Source Configuration and VRC Methodology: An investigation into the impact of varying source and
probe topologies on SE. We introduce a virtual reverberation chamber (VRC) simulation flow designed
to reduce computational complexity by substituting a reverberation chamber by synthesized field
sources. These sources are generated using a randomized plane wave methodology, which allows to
recreate a statistically uniform field without the overhead of physical stirrer and chamber modeling.
High-Voltage Application: A case study applying these simulation flows to assess the shielding
performance of a vehicle battery enclosure, accounting for complex geometries.
