Stochastic electromagnetic-circuit simulation for system-level EMI analysis

A stochastic electromagnetic-circuit modeling workflow is presented for the computer-aided analysis of electromagnetic interference effects in multi-scale, shielded environments. The multi-scale complexity of the environment is tackled through the selective relaxation of the full electromagnetic coupling between different sub-domains when appropriate. The Stochastic Collocation technique is relied upon for the sampling of the random space. The proposed methodology is demonstrated through its application to the modeling of radiated noise coupling to a High Speed Link circuit inside a partially shielded metallic enclosure.
