The study of geometric criteria for electromagnetic shielding

Glyva V.A, Panova E.V.

The paper deals with the estimation of existing approaches to electromagnetic fields and radiation shielding. The metrological base has proved to be insufficient. The new approach to solving this problem has been offered. The paper presents the electromagnetic shields classification in accordance with their structural features for preliminary efficiency estimation, depending on the screened field frequency range with multiple sources of electromagnetic fields. Geometric criteria calculation provides an opportunity to choose the most efficient form of shielding depending on the field source location, its frequency and amplitude characteristics. The experimental study performance and theoretical calculation make it possible to select the technical characteristics of the material meeting the absorption requirements and reflection ratios depending on the screening purposes, as well as to select the geometrical parameters of the electromagnetic screen, based on the criteria developed. Calculations of the advantages of this approach have been performed, restrictions and disadvantages for specific working conditions and safety conditions in the technosphere have been identified.

Keywords: electromagnetic field, screening, measurement.
