The invention pertains to the field of electrical engineering/electronics and relates to a waveguide resonator component, which can be used, for example, in integrated circuits. The problem addressed by the invention is that of producing a waveguide resonator component simply and economically. The problem is solved by a waveguide resonator component in which a substrate ( 1 ) having two waveguides ( 3 ) is present and a microtube ( 2 ) is present as resonator, wherein the resonator has a respective recess ( 4 ) in the region of each waveguide in order to form an intermediate space between the waveguide and the resonator. The aim is additionally achieved by a method in which a sacrificial layer is applied to a substrate having two waveguides and at least a second layer is applied to the sacrificial layer, and thereafter the sacrificial layer is at least partially removed and the resonator is produced in the form of a microtube by rolling up the second layer and possible additional layers.

Filling a mesh hole

Номер: US20220391548A1
Автор: Stefan BOETTNER

The invention relates to a method for filling a mesh hole in a mesh of a 3D digital model. A boundary of the mesh hole is provided by a first closed boundary curve comprising boundary edges connecting boundary vertices of a first plurality of boundary vertices. The method comprises selecting a maximized triple of boundary vertices comprising a first, a second and a third boundary vertex. The selected maximized triple is maximized by selecting a boundary vertex of the first plurality of boundary vertices as the third boundary vertex of the selected maximized triple. The selected maximized triple satisfies a first criterion. The first and the second vertex of the selected maximized triple are connected using a connecting curve from the first to the second boundary vertex.
