Summary: Relevance of the topic: Shielding of ultrahigh frequency electromagnetic interference fields is an important task of physical protection and electromagnetic compatibility improvement in radio electronic devices.
Research purpose: the defining of materials the best to use in electromagnetic shields for ultrahigh frequency interferences rejecting.
Object of research: electromagnetic shields.
Subject of research: shielding efficiency with shielding factor estimation.
Scientific novelty: scientific novelty lies in improving the efficiency of equipment shielding from electromagnetic ultrahigh frequency interferences. It is doing by constructing the shields as three layers of different types of metals (magnetic and non-magnetic), when the intermediate layer is magnetic and the boundary layers are non-magnetic. Furthermore, the three-layer shield greatly increases the shielding factor by raising the mechanism of efficiency by reflection of the electromagnetic wave from layer boundaries.
