Abstract
This article examine design features of alternative study test sites for performing requirements on attenuation of inside electromagnetic waves and screening against outside industrial backgrounds noise. The article discusses the complex screening for alternative study test sites, which includes three phases: screening, absorption of electromagnetic waves and applying the network noise filters.Investigates the principles of screening and absorption of electromagnetic waves. The analysis and selection of optimum screening matter are conducted. The features of the screening to create a holistic protection circuit industrial electromagnetic radiation are analyzed. Calculated depth of penetration of the electromagnetic field in the screen material, equivalent thickness of the mesh material and screening effectiveness of the selected mesh material in the range of frequencies. Provides an overview of matter for absorption of electromagnetic wave are the advantages and disadvantages of different types of materials. It is shown that it is preferable to use composite materials for absorption of electromagnetic wave, because they have a greater band and smaller mass and dimensions.
