An aspect of this invention is to save weight for low frequency shields, especially when it comes to large "Zero gauss chambers”, where the lid could be only made from expensive 5 mm NiFe material. With this shape, manufacturers can use much thinner, lighter and cheaper gauges and achieve the same or an even better shielding factor. Almost any kind of magnetic shield which needs a bottom and/or a lid could use this technology. As shields are used in e.g., satellite navigation systems, the smaller weight may have quite a big influence where weight is critical.
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.
