Laurent Bernard received the B.Sc. and M.Sc. degrees from the Institut National Polytechnique de Grenoble in 2004. In 2007, he received the Ph.D. from the Ecole Centrale de Lyon and the Universidade Federal de Minas Gerais (co-supervision). He is currently Research Engineer at the CNRS and works with the LGEP (Laboratoire de Génie Electrique de Paris). His research interests concern mesh-based numerical methods for electromagnetics and coupled problems.


Keywords: – Unstructured mesh-based numerical methods – Finite Elements, Finite Integration Technique, Generalized Finite Differences, Finite Volumes and Galerkin Discontinuous Method – Frequency and time-domain analysis – Multiphysics, magneto-mechanical coupling – Complex material behaviour within structure simulation – Time-reversal – Wireless charging – Human exposure to electromagnetic fields.
