An aspect of this invention is to save weight for low frequency shields. With this shape, manufacturers can use much thinner, lighter and cheaper gauges and achieve a better shielding factor. Almost any kind of magnetic shield which needs a bottom, and/or a lid could use this technology. Shields are used in e.g., satellite navigation systems, the smaller weight may have a big influence.
English translation: Theoretically the construction can reduce the so-called end-effects due to the mixture of the material directions (parallel and perpendicular). The claim is characterized in that metal, which is used as a shield in the low frequency range because of its chemical and physical properties (eg. B. 2.4545 or 1.3922 (DIN standard), only by mixing the material directions, in the specific example by the use of is combined cylinders and flat disks.
