Problems solved by technology

In order to improve the low-frequency shielding effect of the present invention, the materials used for the construction of the shielding room and the shape of the shielding room are affected. As the frequency decreases, the shielding factor decreases, so the low-frequency shielding effect is poor
[0005] It can be seen that the existing ele...

Abstract

The invention provides an electromagnetic shielding room. The electromagnetic shielding room comprises a shielding shell, wherein a closed electrometric shielding space is defined inside the shielding shell, the wall surface of the shielding shell comprises a permalloy shielding interlayer, a supporting layer and an aluminum plate shielding interlayer from inside to outside, and the permalloy shielding interlayer and the aluminum plate shielding interlayer are fixed to the inner side and the outer side of the supporting layer respectively. The electromagnetic shielding room not only adopts permalloy to shield a low-frequency magnetic field, but also adopts aluminum plates to shield a high-frequency electromagnetic field, and therefore the high-frequency shielding effect is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic fields, in particular to a high-performance electromagnetic shielding room. Background technique [0002] The electromagnetic shielding room refers to the use of certain technical means to shield the electromagnetic interference generated by the earth's magnetic field, nature, and humanities, and create an environment without electromagnetic interference. Under the environment, various scientific research activities can be carried out. The electromagnetic shielding room is an important infrastructure in modern scientific research. For example, in the field of biomagnetism research, because the magnetic field of the organism under study is extremely weak, it is often submerged in the electromagnetic interference of the disorderly environment. Therefore, it is necessary to place the organism in A shielded room without electromagnetic interference can measure the weak magnetic field signals o...
