Possibility theory is briefly presented and proposed for the evaluation of epistemic uncertainty in electromagnetic-compatibility models. In particular, fuzzy sets are exploited to describe some unknown/uncontrolled model parameters which cannot be rigorously treated through probability theory, since their statistical distribution is unknown. A hybrid approach is used to combine such possibilistic...
This work presents a theoretical rationale for the substitution of radiated-susceptibility (RS) verifications defined in current aerospace standards with an equivalent conducted-susceptibility (CS) test procedure based on bulk current injection (BCI) up to 500 MHz. Statistics is used to overcome the lack of knowledge about uncontrolled or uncertain setup parameters, with particular reference to the...
In this work, the role of proximity and possible trace asymmetries on the generation of common mode (CM) voltages and currents in a pair of differential lines (DLs) printed in close proximity on the same PCB substrate is analyzed. To this end, an approximate circuit interpretation of mode conversion in terms of distributed voltage and current sources is exploited to preliminary identify relevant parameters...
