Participants : Kakon Sem Fure (Master student), Margot Sirdey (PhD Student), Sébastien Pernet (ONERA), Sébastien Tordeux Trefftz methods are known to be very efficient to reduce the numerical pollution when associated to plane wave basis. However, these local basis functions are not adapted to the computation of evanescent modes or…
Participants : Margot Sirdey (Doctorante) Sébastien Tordeux, Sébastien Pernet (ONERA) Three dimensional electromagnetic waves simulation is an important issue in many applications. Industrial simulation frequently involves the solution of a large linear system. When resorting to direct methods (LU decompositions) the necessary memory for the inversion of the matrix increases…
