“…Some attempts were made to introduce novel global SA methods (Marelli and Sudret, 2014) to the field of EMC measurements performed in ACs, e.g. Bingler et al (2021Bingler et al ( , 2022b. The main contribution of this work is the extension of the application area of the method of Sobol' indices (Sobol, 1993) to RCs.…”

Purpose Global sensitivity analysis (SA) by means of Sobol’ indices enhanced with different surrogate modeling techniques is performed in this work. The purpose is to investigate the influence of measurement uncertainties and the environment characteristics themselves on the desired field uniformity in reverberation chambers (RCs). This yields an efficient apparatus for the stirring and chamber design process. Design/methodology/approach The technique of Sobol’ indices, as a candidate of global SA methods, is suitable for high fluctuations due to its robustness, which can be addressed to the stochastic nature of the RC environment. The aim of using surrogate modeling techniques is to compute the indices efficiently with a moderate number of required simulations. The powerfulness of this approach is introduced in a simple numerical example in which the physical phenomena can be identified more straightforwardly. Findings This method can provide useful knowledge in the lower frequency range, where the ideal properties of the electromagnetic field in RCs cannot be established, and the importance of the setup parameters can vary from configuration to configuration. In addition, it can serve as a basis for setup adaptation during parallelized electromagnetic compatibility tests, which would result in a more time- and cost-saving option in industrial applications in the future. Originality/value Despite the previous attempts, a profound investigation of multiple setup parameters is still a hot topic. The main contribution of this work is the extension of the application area of the method of Sobol’ indices to RCs, which has not been done so far.

“…However, a large variety of algorithms exists when it comes to metamodeling. In EMC/SI/PI domain some methods have shown great performances like Kriging [2] [3] [4], support vector machines [5] or polynomial chaos [6] [7] to name a part of them. For this study, we choose to use Kriging due to its overall good performance.…”

This article presents a methodology using machine learning techniques for defining printed circuit board (PCB) design rules in order to reduce signal integrity (SI) or electromagnetic interference (EMI) issues. The scenario illustrating the situation for which these rules must be defined is modelled with a 3D EM solver available on the market and simulations are run with varying parameters in order to obtain a representative sample of the design space. This data set is then used to train a surrogate model (i.e. a metamodel) of the scenario based on kriging algorithm. Using this surrogate model, more than ten thousands of simulations are computed in a decent time. The surrogate model estimations allow to estimate the sensitivity of the varying parameters with respect to some specifications (crosstalk level and insertion loss). Finally, an analysis of output values for which some requirements (crosstalk level, insertion) loss are not fulfilled provide some insights about possible adjustment of guidelines in terms of parameter ranges. Finally, a practical design example is given to illustrate the methodology.
