Special Issue: The 13th International Symposium on Electric and Magnetic Fields (<scp>EMF</scp> 2023)

On behalf of the Editorial Board, we are pleased to present a selection of papers related to the 13th International Symposium on Electric and Magnetic Fields (EMF 2023), held in Marseille, France, on August 29–31, 2023. The EMF symposium series, whose first edition was held in Liège, Belgium, in 1992, aims at building a bridge between recent research advances in mathematical and numerical modeling of electromagnetic fields and the growing number of industrial problems requiring such techniques. The 13th edition was organized at Aix-Marseille Université and attracted 75 participants from 16 countries. Among the 65 presentations in the symposium program, 13 papers were selected for publication in this special issue of the International Journal of Numerical Modelling: Electronic Networks, Devices and Fields. The high scientific and technical quality of the symposium is well reflected in the quality of the manuscripts contained in this special issue. Three broad topics were covered during the 13th edition of the symposium. The first major topic considers the mathematical modeling of electromagnetic problems in view of their eventual numerical solution on computers, with contributions on the calculation of forces [1], homogenization [2] and material models [3, 4]. The second major topic treats general methodological advances in numerical methods, from quasi-static [5, 6] to high-frequency problems [7, 8]. The third major topic is the application of modeling to the study, design, and optimization of a wide range of technological devices, spanning low- to high-frequency electromagnetic regimes [9-13]. This underlines the spirit of the conference, which encompasses both theory and practical applications. We express our gratitude to the members of the EMF scientific committee—Florian Bentivegna, Oszkár Bró, Markus Clemens, Stéphane Clénet, Willie Cronje, Luc Dupré, Johan Gyselinck, Kay Hameyer, Lauri Kettunen, Vincent Mazauric, Gérard Meunier, Axel Modave, Ronan Perrussel, Martin Petrun, Adel Razek, Maurizio Repetto, Ruth Sabariego, Sebastian Schöps, Jan Sykulski—as well as to all the reviewers who provided the necessary volunteer time and expertise to conduct a fair and detailed review, ensuring high publication standards for the selected manuscripts. We also thank the staff from the Association des Ingénieurs de Montefiore (AIM), and especially Céline Dizier and Louisa Kara, for their help organizing the EMF symposium series. We hope that you will enjoy reading this selection of articles.
