The reflection of a plane‐electromagnetic wave from a rough perfect conductor is investigated. The roughness is represented by hemispherical bosses whose radii and mutual distances are small relative to the wavelength. This problem is solved taking into account the electromagnetic interaction of the bosses. Aside from throwing some light on the lim...

L'objectif principal retenu pour cette recherche a été centré sur l'étude et la mise au point d'un procédé électromagnétique de coulée continue de billettes de petits diamètres. Les deux premiers chapitres sont consacrés à l'exposé du principe, au dimensionnement et au chiffrage des performances de deux dispositifs électromagnétiques dénommés "Buse...

A numerical approach of the reconstruction of an inhomogeneous slab is described, the relative permittivity or the index of which are unknown. This one-dimensional dielectric medium is assumed to be linear, isotropic and non-magnetic, its conductivity being known, generally equal to zero. Its frequency independent permittivity arbitrarily varies, n...
