Sur une approximation des champs propagés par les équations de Maxwell instationnaires, homogènes, à l'extérieur d'un domaine borné

Abstract: This Note is devoted to obtaining an approximate integral formula giving the value of the electromagnetic field at a space–time point from values measured on a polyedral surface . The main result leads to time-localized calculations, geometrically split in space along the adaptative parts of , and optimisable as a function of the point''s distance. To cite this article: V.
