Abstract: The present invention relates to a method for manufacturing an electronic or electrical system, the method comprising the layer-free production of at least one physical structure (101, 102) which is designed to guide electromagnetic waves, using at least one additively operating apparatus, wherein the layer-free production of the spatial, layer-free structure comprises the simultaneous or sequential application and/or removal of one or more materials in the spatial arrangement, as a result of which the electronic or electrical system is partially or completely formed. The invention further relates to a system which is manufactured in accordance with the method.

Abstract: The invention relates to a method of manufacturing technical radio frequency functional structures comprising the steps of providing a base body determining the shape of the functional structure and applying an electrically conductive layer to the shape-determining base body by means of wetting the base body with a dispersion containing microparticles and/or nanoparticles.

Abstract: An ultrasound head of the type suitable for medical ultrasound therapy has a housing with an opening in which a resonator assembly is insertable. The resonator assembly is mounted in the opening of the housing so as to be removable. The assembly includes a carrier for a ceramic resonator disc, the carrier having an outwardly flanged edge which is received against an inside shoulder of the housing surrounding the opening, so that the carrier projects at least partially out of the opening. A pressing mechanism is provided for maintaining the assembly tight against the inside shoulder by applying pressure from the interior of the housing.
