    摘要: A solvent transfer printing method for applying a pattern made of a non-soluble material and non-dispersible on the surface of an object. The method includes the steps of: m1/forming a pattern on a surface of a solvent-soluble substrate, m2/depositing the solvent-soluble substrate on the surface of a solvent bath, on the side of the substrate opposed to the side on which the pattern is applied, in order to dissolve partially the substrate, m3/dipping the object in the bath, so that the surface of the object comes into contact with the pattern, m4/getting the object, on which the pattern is applied, out of the bath, and b 5/drying the object.

    摘要: The invention concerns an antenna, comprising at least two non-ferrous metal plates, at least one first plate forming a radiating portion and a second plate forming a mass plane, at least one substrate, arranged between the mass plane and the radiating portion, and an excitor of length at least equal to the thickness of the substrate, extending between the mass plane and the radiating portion and connected to the radiating portion, and adapted to supply the antenna, characterised in that the substrate is a dispersive ferromagnetic substrate, called dispersive ferrite presenting, as magnetic features, a high relative magnetic permeability comprised between 10 and 10,000 and a high magnetic loss tangent greater than 0.1, said antenna comprising means for gradually and locally reducing magnetic features of the dispersive ferrite.
