PIERS2019 Rome Focus/Special Sessions

SC1: Stochastic Methods in Electromagnetic Compatibility

Organized by Dr. Gabriele Gradoni (University of Nottingham) and Prof. Valter Mariani Primiani (Universita Politecnica delle Marche)

Session's Information:

The growing complexity in electronic circuit and systems requires statistical electromagnetic approaches that capture the wide variability in physical geometries, material parameters, and excitation source characteristics. In electromagnetic compatibility (EMC), safety margins in immunity/emission problems become statistical variables that call for the definition of required confidence levels. Bridging deterministic and statistical approaches spark new perspectives in complex EMC systems modelling. Wave chaos theory offers a unique bridging platform for modeling wave systems with an arbitrary number of degrees of freedom. The theory stands on semiclassic analysis methods, random matrix theory and polynomial chaos expansions. Real life engineering scenarios where wave chaos modelling is relevant are: - characterization and propagation of radiated emissions from multifunctional digital electronics; - propagation of interferences through aperture coupled avionic/naval compartments; - wireless channel emulation through electromagnetic reverberation chambers; - signal diffusion through networks of cables; - coupling and crosstalk in cable bundles; - shielding prediction of cables-cabinets; - characterization of material composite properties. This session welcomes – but is not limited to - contributions that describe innovative theoretical and experimental methods used to characterise those scenarios.
